Analyzing the Two-Dimensional (2+1) REMPI Spectra of Bromine and Carbon
Experimental investigation have been carried out for dissociation/ionisation of methyl bromide using time of flight mass spectrometer, and the mass signals mle = 12, 13, 14, 15, 79, 81, 129 and 131 were assigned to H+, C+ CH+, CH2+, CH3+, Br+ (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 5P4P3/2←4P2P1/2 and 5pAP5/2 ←4P2Pv2 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.
