Vibrational spectra and stereochemistry of mono- and polysaccharides

A comparative study of the IR and Raman spectra of D-glucose anomers is reported. The spectra were found to differ between the anomers, despite the absence of symmetry elements in the anomer molecules. The results of theoretical calculations are systematized; it was found that the skeletal CiOi or CiO(i+1) (i=1, 2, 3, 4, 5) bond is characterized by a specific set of frequencies of normal vibrations, which have predominant contributions from the vibrations of atomic groups involving these bonds to the potential energy distribution (PED). The frequencies of normal vibrations with the major contribution to PED from CO and CC bonds are well separated and differ between the D-glucose anomers. The C5C6 bond has the greatest number of normal vibrations with predominant contributions to PED. Model calculations of vibrational spectra are reported for D-glucose anomers with modified (β→α and α→β) conformations of the CH₂OH group. B. I.

An interview with I.M. Kolthoff

Izaak Maurits Kolthoff was born in 1894, in Almelo, Holland. He studied pharmacy at the University of Utrecht, and was awarded a Ph.D. in chemistry there in 1918. He served as Conservator of the Pharmaceutical Institute at the University from 1917 to 1927 and as a privat docent (lecturer) from 1924 to 1927. In 1927 Professor Kolthoff began his long association with the University of Minnesota, serving as Professor and Chief of the Division of Analytical Chemistry until 1962 and since then as Professor Emeritus. He is a member of the United States National Academy of Sciences, a foreign member of the Royal Flemish Academy of Sciences and of a number of other learned Societies thoughout the world.

Vibrational spectra and stereochemistry of mono-and polysaccharides. II. α-anomers of D-glucose and D-galactose. Glucitol and galactitol

The IR and Raman spectra of D-glucose and D-galactose α-anomers are compared with the corresponding spectra of the related polyatomic alcohols glucitol and galactitol. Experimental data on the frequencies and modes of normal vibrations and on the contributions of normal vibrations involving particular skeletal CiOi and CiC(i+1) bonds to the potential energy distribution (PED) are compared with the results of theoretical calculations. The α-anomers of D-glucose and D-galactose with different configurations of the C4C4 and C4H4 bonds are characterized by substantially different sets of frequencies with prevailing contributions to PED from the CiOi and CiC(i+1) bonds. The similar bonds of glucitol and galactitol are also characterized by specific frequency sets. Particular CiOi and CiC(i+1) bonds have different numbers of “localized” frequencies. B. I.

In memoriam

Prof. Ing. Zdeněk Šolc, CSc (21 September 1931–30 September 2006) Prof. Zdeněk Šolc was born in 1931. After finishing his university studies, he joined the University of Pardubice where he remained for more than 50 years. He started to work at the Department of Physical Chemistry. His main fields of interest were: preparation of monocrystals, crystallization from solutions, measuring of physical and chemical properties of solutions. In the 1960's he turned to inorganic technology, studying inoranic pigments and he moved to the Department of Inorganic Technology. In this vast area of science, he achieved his greatest successes, and pigments became his ever-lasting passion up to the end of his life. The research in the field of crystallisation was oriented to development of liquid crystals for use in temperature indication, and materials for integrated circuits; besides that a school of inorganic pigments was formed (M. Trojan, Z. Šolc, D. Brandová) whose main orientation is mixed oxide materials for use in ceramics and enamels. A predominant part of the mentioned research activities was pursued at KAnT in 1990–1996, when the Department was headed by Professor Ing. Zdeněk Šolc. Most of Prof. ŠolcŠs projects were focused on the reactivity of inorganic pigments and powder materials, research of their high-temperature syntheses and rating of their physical and chemical properties. He applied mainly simultaneous thermal analytical techniques: thermogravimetry, differential thermal analysis using dynamic measuring conditions and quasi-isothermal and quasi-isobaric ones, moreover emanation thermal analysis and thermal conductivity measurements. Prof. Zdeněk Šolc was a creative scientist. He published more than 50 scientific papers in international journals and wrote 10 textbooks. He was the author of almost 100 lectures of conferences held in the Czech Republic and foreign countries. He had a silent but a very kind personality and he will be missed very much both by the local and the international communities. Requiescat in pace     

Vibrational spectra and stereochemistry of mono- and polysaccharides. III. β-methyl-d-glucoside, α-methyl-d-glucoside,and β-methyl-d-xyloside

The IR and Raman spectra of β- and α-methyl-D-glucosides and β-methyl-D-xyloside are compared. Experimental data are correlated with theoretical calculations of the frequencies of normal vibrations. Predominant contributions (20% and more) of particular CiOi and CiC(i+1) bonds to the potential energy distribution of normal vibrations (i.e., localization of vibrations on these bonds, which form skeletons of monosaccharide molecules) are estimated. This approach is used to interpret the main distinctions between the IR and Raman spectra of the test compounds. The use of vibrational spectra in selective analysis of certain functional groups is discussed. It is shown that replacing the hydroxyl group at C1 has a specific effect on the predominant localization of vibrational modes in particular skeletal bonds (mainly in C1O1) of the monosaccharide molecules.

Professor Cristofor I. Simionescu on His 70th Birthday

Professor Cristofor I. Simionescu was born on July 17, 1920, in Dumbraveni-Suceava. His father was a high school teacher, and young Simionescu went to elementary school in his home town. After completing elementary school he went to Jassy and attended the prestigious “National Lyceum,” the roots of which stem from the “Michailean Academy.” He then began studies at the Polytechnic Institute of Jassy at the Faculty of Chemical Engineering. As a young student he was known for his enthusiasm and was recognized as an excellent young scientist. In 1944 Cristofor Simionescu graduated mugna cum lade from the Polytechnic Institute in Jassy. He obtained his first scientific degree in organic technology, i.e., Doctor of Technical Sciences, in 1948, and became Associate Professor at the Polytechnic Institute. In 1951 he was promoted to Full Professor and was appointed to the Chair of Natural and Synthetic Macromolecules. From 1953 until 1976 Professor Simionescu was Rector of the Polytechnic Institute of Jassy.

Vibrational spectra and stereochemistry of mono- and polysaccharides. IV. α-methyl-d-glucoside, α-methyl-d-galactopyranoside,and α-methyl-d-mannopyranoside

The IR and Raman spectra of α-methyl-D-glucoside (αMDG), α-methyl-D-galactoside (αMDGal), and α-methyl-D-mannoside (αMDM) are compared. The main distinctions between these spectra have been interpreted using experimental and theoretical data on the frequencies and modes of normal vibrations and on the potential energy distributions over particular bonds and atomic groups of the substances under investigation. Spectral characteristics that are determined by different configurations of C−O (CH) groups attached to C2 and C4 atoms and different conformations of C6H₂O6H fragments have been revealed. It has been established that replacement of hydroxyls at C1 with methoxy groups significantly increases the number of frequencies of normal vibrations that are localized mostly in the C1C2 bonds (particularly in αMDGal). For the αMDGal molecules with axial C4O4 groups, the number of frequencies of normal vibrations that show predominant contributions of these groups of PED is smaller. For the αMDM molecules, in which the conformation of CH₂OH groups (with respect to rotation around the C5C6 bonds) differs from that in αMDG and αMDGal molecules, most vibrations are localized in the C6O6 bonds rather than in the C5O5 bonds. This fact is very important in correlating the vibrational spectra and structural properties of mono- and polysaccharides. B.I. Stepanov Institute of Physics, Belarus Academy of Sciences. V.
