Thermal electron capture by some halopropanes

Thermal electron attachment rate constants for CF 3CHClCH 3, CF 2ClCFClCF 3 and CBrF 2CH 2CH 2Br have been measured with electron swarm method. Corresponding rate constants are equal to 7.6×10 −11, 5.5×10 −9 and 1.5×10 −8 cm 3 molecule −1 s −1, respectively. The dissociative electron attachment (DEA...

Zusammenfassung:Thermal electron attachment rate constants for CF 3CHClCH 3, CF 2ClCFClCF 3 and CBrF 2CH 2CH 2Br have been measured with electron swarm method. Corresponding rate constants are equal to 7.6×10 −11, 5.5×10 −9 and 1.5×10 −8 cm 3 molecule −1 s −1, respectively. The dissociative electron attachment (DEA) spectra for nine haloalkanes have been determined using negative ion mass spectrometry. The correlation between rate constants, position of the DEA peaks and vertical attachment energy (VAE) available in literature has been demonstrated.
