Conclusions It has been shown by the EPR method that the colored products formed by the action of a mixture of ozone and oxygen on the solid hydroxides of the alkaline-earth metals are ozonides containing the molecular paramagnetic ion O3

Single stage reactions of 2-formylbenzoic acids with substituted 2-(1-aminoalkyl)phenols and 2-amino-phenylcarbinols give
a novel series of isomeric isoindolobenzoxazinones. X-ray analysis was used to study the molecular structure of 9-bromo-5,5-diphenyl-5H-isoindolo[2,1-a][1, 3]benzoxazin-11(6aH)-one and 2-bromo-8,10-dimethyl-10H-isoindolo[1,2-b][1, 3]-benzoxazin-12(4bH)-one. 相似文献

The recyclization of derivatives of 2-aryl-5-benzylfuran containing a tosylamine fragment to give indoles has been studied.
If the tosylamino group is in the ortho position of the aryl substituent, the recyclization proceeds such that the furan ring
may be seen as a formal equivalent of a 1,3-diketone. If, on the other hand, the tosylamino group is in the ortho positions
of both the aryl and benzyl substituents, the recyclization proceeds through a pathway, in which the furan ring acts as the
equivalent of a 1,4-dicarbonyl compound.

Differential cross sections and polarization observables for the elastic and inelastic scattering of 800-MeV protons on 16O and 20Ne nuclei are calculated on the basis of the theory of multiple diffractive scattering and the α-cluster model involving dispersion. The single-particle nucleon-density distributions obtained within the α-cluster model involving dispersion are used in the calculations. The differential cross sections and polarization calculated for elastic and inelastic p16O and p20Ne scattering are compatible with available experimental data. The spin-rotation functions calculated for elastic p16O and p20Ne scattering within the independent-nucleon model differ qualitatively from their counterparts calculated within the α-cluster model involving dispersion. 相似文献

The formation of bound excitons of the donor type was observed in LiH and LiD single crystals activated by 4d or 5d transition elements (Rh, Ru, Ir). The bound excitons were found to form under direct optical excitation of impurity ions. 相似文献
