Photolysis of 1,1′-ferrocenedicarboxylic acid

Summary 1,1-Ferrocenedicarboxylic acid undergoes decomposition under the influence of light with a rupture of the C-Fe bond and the formation of the dimer of cyclopentadienecarboxylic acid.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 1694–1695, September, 1965     

Acid-base interactions of complexes of substituted triazoloporphyrazines in media containing acetic acids

Acid-base interactions of Cu(II) and Ni(II) complexes of substituted triazoloporphyrazines in benzene-AcOH and dichloromethane-AcOH mixtures were studied and quantitative characteristics of equilibria were obtained. The replacement of one pyrrole ring in porphyrazine molecule by triazole ring was shown to increase the basicity of a macrocycle; the N(1) atom of triazole ring was proposed to be the center of protonation.     

Stimulated radiation pressure acting on an atom nonadiabatically interacting with the field of counterpropagating frequency-modulated waves

The stimulated radiation pressure acting on an atom nonadiabatically interacting with the field of counterpropagating frequency-modulated waves is shown to reach high values typical for the rapid adiabatic passage of the instantaneous frequency of the field of the counterpropagating waves through resonance with an atomic transition. Under the appropriate choice of interaction parameters, the radiation pressure changes insignificantly in a wide range of atomic velocities.     

Substituent and Solvent Effects on The Electronic Absorption Spectra of Phosphapyrimidine Derivatives

U.v spectra study of phosphacgclic compounds with tetracoordinated ring phosphorus atom has been an object of a rather limited number of WOZkS. There are only few works on U.V. absorption spectra of cyclic phosphonitriles which reveal a specifio character of their Π-electronic structure¹; besides, there are some data on a significant low - frequency shifting of the electronic spectrum of 1.1 - diphenylphos-phabemene against that of benzene². This communication presents an analyisis of the experimental findings on electronic absorption spectra of a Wide variety of substituted phospha-pyrimidines, PhP, (1,2,6 - phosphadiazines) for elucidating the nature of the observed absorption ban and for studying electronic distribution as well as separate characteristics of the php moLecules in the ground and excited states.
