Abstract

Emission spectra of the CH(A2Δ-X2Π) transition produced in the electron impact dissociation of acethylene have been measured. The rovibrational distributions of CH(A2Δ) depend on the electron impact energy; the rotational temperature of CH(A2Δ, v′ = 0) varied from 3200 K at 17 eV to 2500 K at 100 eV, and the ratio of the vibrational populations (P(v′ = 1)/P(v′ = 0)) varied from 0.45 at 17 eV to 0.80 at 100 eV.
