HF infrared emission from the reactions of atomic fluorine with methylcyanide, methylisocyanide, dimethylsulfide and dimethyldisulfide

Abstract

In the reactive systems F + CH 3CN, F + CH 3NC, F + CH 3SCH 3 and F + CH 3SSCH 3 infrared emission spectra were recorded from HF in the fundamental region under relaxation-free conditions. The reported vibrational distributions are for F+CH 3CN:N υ=1 :N υ=2 :N υ=3 =0.38:0.42:0.20 for F+ CH 3NC:N υ=1 :N υ=2 :N υ=3 :N υ=4 :=0.46:0.32:0.17:0.05;for F+CH 3 SCH 3:N υ=1 :N υ=2 :N υ=3 :=0.36:0.39:0.25;for F+ CH 3SSCH 3:N υ=1 :N υ=2 :N υ=3 :N υ=4 :=0.43:0.35:0.19:0.04 Rotational distributions are drawn up and discussed for F + CH 3CN and F + CH 3SCH 3. There is strong evidence for the existence of two microscopic channels in all four systems investigated.
