Abstract

The energy transfer reaction of metastable He (23S) with CH3CN has beeninvestigated. Near-violet emission spectra of CN (B-X) and CH (A-X) wereobserved. Based uPOn the spectra of excited fragment we estimated the formation rateconstant and vibrational POpulation of CN (B). The reaction mechanism were alsodiscussed.
