Rearrangement processes with the successive splitting out of HF and CO2 molecules, the contribution of which to the scheme of the fragmentation of the negative molecular ions reaches 99%, are realized in the resonance capture of thermal electrons by molecules of organofluorine compounds (derivatives of di- and tetrafluorocinnamic acids and 1,4-diaryltetrafluorobutadiene).Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1547–1549, July, 1990. 相似文献

Appearance energies have been measured for negative ions formed in the gas phase upon dissociative capture of electrons by molecules of cyclopentadiene, pyrrole, selenophene, thiophene, furan, and furan derivatives. From an analysis of the enthalpies of formation of the fragmentation products, it has been established that electron capture by molecules of C4H4X (X=O, S, Se, NH, CH2) leads to the formation of ions with cyclic and acyclic structures.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 590–592, March, 1991. 相似文献

Phenol, chlorobenzene and chlorophenol isomers: resonant states and dissociative electron attachment
Khatymov RV Muftakhov MV Mazunov VA 《Rapid communications in mass spectrometry : RCM》2003,17(20):2327-2336
This paper reports a study of resonant dissociative electron attachment (DEA) to the phenol, chlorobenzene, p-, m-, and o-chlorophenol molecules. On the basis of spectroscopic and thermochemical approaches the resonant states of the molecular negative ions (NIs) and the structures of some dissociative decay products are assigned. In the electron energy range up to 3 eV, DEA processes are determined by the two 2[pi*]-shape resonances resulting mainly in formation of [M-H]- and/or Cl- ions. At higher electron energies the energy correlation between peaks in the negative ion effective yield curves and bands of UV spectra allowed identification of the core-excited resonances. The peculiarities of Cl- ion formation and the vibrational fine structure on the effective yield curves of the [M-H]- ions are discussed. The mass spectrometric procedures for measurement of relative cross sections for NI formation are described. 相似文献
