The use of DART mass spectrometry for express confirmation of empirical formulas of heterocyclic compounds
No full textThe results of studying the possibility of using DART spectrometry with a time-of-flight mass analyzer to confirm the elemental composition of heterocyclic compounds are presented. The method makes it possible to rapidly determine the molecular weight and to calculate the empirical formula of organic synthesis product. © 2010 Springer Science+Business Media, Inc

Investigation of the astrophysical ³⁶S(p,γ) ³⁷Cl reaction AT Ep=1975...2190 keV
No full textThe ³⁶S(p,γ) ³⁷Cl reaction was investigated in the proton energy range Ep=1975-2190 keV. The observed resonance strengths were evaluated. The γ-decay schemes of the resonances at Ep=2037, 2058, 2069, 2080, 2122 and 2165 keV were constructed and the total γ-widths were determined. The astrophysical ³⁶S(p,γ) ³⁷Cl reaction rate was estimated.Представлено результати дослiджень реакцiї ³⁶S(p,γ) ³⁷Cl в областi енергiй протонiв
