摘要: Abstract The A 2 1 -X E electronic spectrum of jet-cooled methoxy radical has been examined by the LIF technique. Two newly discovered vibrational bands 2930 and 1390 cm −1 are assigned to ν (totally symmetric C-H stretching) a degenerate 5 mode, respectively. predissociation, CH 3 O → + in state is elucidated threshold energy deter- mined as 5100 from potential minimum. For O-Ar complex, reduced about 100 .
