Experimental investigation have been carried out for dissociation/ionisation of methyl bromide using time of flight mass spectrometer, and the mass signals m/e = 12, 13, 14, 15, 79、81、129 and 131 were assigned to H+、C+ 、CH+ 、CH2+ 、CH3+iBr+ (i = 79, 81)、(CH)2iBr+ (i=79, 81). Next, two resonant peaks of 79Br+*/ 81Br+* were observed at 280.41nm and 281.74nm due to spin-forbidden 5p and 5p which have not been reported before. At last, the C REMPI spectra found near 280.34nm、286.94nm and 284.21nm were assigned, too, which compared with the predicted wavelength values.
