The efficient Stokes and anti-Stokes laser emissions with Raman frequency shift at about 2960 cm?1 are excited in a food C12H22O11 sugar (sucrose) single crystal under pulsed pumping. Other (χ(2) + χ(3)) effects of the parametric Raman generation are also detected. 相似文献

Polarized absorption and emission spectra, and temperature dependences of the fluorescence lifetimes and intensities for the chromium-doped LiNbGeO5 laser crystal are presented. Crystal symmetry and comparison with the infrared fluorescence properties of the Cr-doped Mg2SiO4 and Y3Al5O12 laser crystals seem to identify the active center as a Cr4+ ion in a tetrahedral site. 相似文献

The thermolysis of 10-R,9-R1,9-R2-4a,10a-epidioxyperhydroacridines has given 1-R-3-[-(2-oxocyclohexyl)alkyl]hexahydroazepin-2-ones which have been reduced to the corresponding 2-hydroxycyclohexyl derivatives. Hydrolysis of the compounds obtained led to 3-[-(R-amino)butyl]hydrocoumarins.For communication 22, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 650–656 May, 1985. 相似文献

In order to establish quantitatively the reducibility of halogen-substituted components of nucleic acids, the half-wave potentials (E1/2) of their electrochemical reduction have been determined. The electrochemical reduction of all compounds takes place in the interval from –0.5 to –1.8 V and consists in the splitting off of the halogen atom (iodine, bromine) from the given molecule. The iodine derivatives are reduced much more readily (500–800 mV) than the bromine derivatives.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1404–1408, October, 1992 相似文献

Compounds that contain a hydrogenated azolopyridine structure are formed in the reaction of various types of 1,5-diketones with ethanolamine, o-aminophenol, o-phenylenediamine, and aroylhydrazines; compounds that include a hydrogenated azinopyridine structure were obtained by the reaction of diketones with 3-aminopropanol and anthranilic acid. The hydrocyanation and oxidation of the compounds obtained were studied.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 240–245, February, 1979. 相似文献

Summary The physicochemical properties of the oils of the seeds of seven plants of the family Cruciferae —Cakile maritima, Sisymbrium altissimum, Sisymbrium Loeselii, Descurainia Sophia, Erysimum cheiranthoides, Brassica amoracioides andCrambe pontica — have been studied and their fatty acid compositions have been determined. The results obtained showed no marked differences from those given in the literature.Zaporozhe Medical Institute. Ukrainian Scientific-Research Institute of the Oils and Fats Industry.

The HF RADMON system monitors radiation environment in the region of the forward calorimeter of the CMS setup. Measurements of neutron fluxes at energies of 7, 8, and 13 GeV are carried out; estimates of the radiation shielding efficiency are obtained. Modernization of the system for operating under high luminosity conditions is completed and its capabilities to be used as an additional luminometer are confirmed. 相似文献

The electrical conductivity of SmS polycrystals has been studied in the temperature range 300?C870 K. It has been shown that, at 300 K ?? T ?? 700 K, the concentration of conduction electrons is determined by electron transfer from impurity donor levels, and at T > 700 K, by that from the samarium 4f levels. 相似文献
