The charge separation and electron capture induced decomposition reactions of doubly charged [C_7H_7NO]~(++), [C_7H_5O]~(++) and [C_6H_7N]~(++) ions produced in the ion source by electron impact from benzoylamide were studied in the present work. The transition states were discussed in detail according to the kinetic energy releases in the charge separation processes and the intercharge distances in the transition states.

The charge separation and electron capture induced decomposition reactions of doubly charged [C_7H_7NO]~(++), [C_7H_5O]~(++) and [C_6H_7N]~(++) ions produced in the ion source by electron impact from benzoylamide were studied in the present work. The transition states were discussed in detail according to the kinetic energy releases in the charge separation processes and the intercharge distances in the transition states. Two kinds of structures were postulated for [C_7H_7NO[~(++) ion. The metastable ion is of a quinonoid stucture due to the amino rearrangement, otherwise, the stable ion is of a structure like the corresponding singly charged ion [C_7H_7NO]~+. The structural identity of [C_6H_7N]~(++) from benzoylamide and aniline, respectively, was also discussed. In ECID spectra, the favourable reaction channels were the neutral losses containing O and N atoms. The ECID reaction is independent of the target gas pressure in a certain target gas pressure range.

The decomposition of doubly charged ion formed in the ion source is dominant by the losses of H, C_2H_2, C_2H_4 and HR(Rrepresents substituent). [C_(12)H_8]~(2+), [C_(12)H_6]~(2+) and [C_(10)H_6]~(2+) among others are the most stable product ions. The substiuents effect is Various in different decomposition reactions, and in some cases...

The spectral features of target-gas and several interfences by Fourier transform infrared spectrometer (FTIS) are analysed. Infrared spectral pattern-recognition methods are applied to the environmental monitoring. Selected standard samples are trained, the stable weight values and threshold value of the system are obtained. This method is suitable for real-time remote detection of hazardous-gas in local environment. It shows very high discrimination results. The results of its practical examples for local atmospheric environment monitoring prove that pattern recognition methods are quite effective for the fast discrimination specific component of environmental monitoring.
