Thermal electron capture by some chlorobromopropanes

Abstract

Thermal electron attachment rate constants for CH2ClCHBrCH3 and CH2ClCH2CH2Br have been measured using electron swarm method. Corresponding rate constants are equal to 3.5×10-10 and 2.5×10-10 cm3 molec-1 s-1, respectively. Parallely, negative ion mass spectra of these compounds as well as CH2FCH2Br, CH2ClCH2Br, CH2BrCH2Br and CF3CHClBr has been measured with negative ion mass spectrometry method. The rate constants have been compared with the negative ion mass spectra.
