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

In the reactive systems F + CH3CN, F + CH3NC, F + CH3SCH3 and F + CH3SSCH3 infrared emission spectra were recorded from HF in the fundamental region under relaxation-free conditions. The reported vibrational distributions are for F+CH3CN:Nυ=1:Nυ=2:Nυ=3=0.38:0.42:0.20 for F+CH3NC:Nυ=1:Nυ=2:Nυ=3:Nυ=4:=0.46:0.32:0.17:0.05;for F+CH3SCH3:Nυ=1:Nυ=2:Nυ=3:=0.36:0.39:0.25;for F+CH3SSCH3:Nυ=1:Nυ=2:Nυ=3:Nυ=4:=0.43:0.35:0.19:0.04 Rotational distributions are drawn up and discussed for F + CH3CN and F + CH3SCH3. There is strong evidence for the existence of two microscopic channels in all four systems investigated.
