AbstractHigh-resolution zero kinetic energy (ZEKE) photoelectron spectrum of methyl bromide has been obtained using vacuum ultraviolet laser single photon excitations. The dominant feature of the spectrum is the origin band of the transition −X ~ 2 E 3/2 −X 1 A 1 −X~2E3/2−X1A1. The excitation of the totally symmetric vibrational mode, ν 2 (CH 3 ν2(CH3 symmetruc deformation), is observed. The 3 1 1 311 hot band is also present. All the bands obtained show similar rotational contours. Simulation of the rotational contour of the origin band yields the accurate first ionization potential of methyl bromide (85022.4±1.0cm −1 85022.4±1.0cm−1) and also the rotational constants of the X ~ 2 E 3/2 X~2E3/2 ground electronic state of the cation. The non-resonant two-photon ZEKE photoelectron spectrum of furan is also presented.
