Abstract

We report the rotationally resolved, one-photon threshold photoelectron spectrum of the methyl radical, CH₃, produced by supersonic-jet, flash pyrolysis. Only rotational transitions with ΔK=0, ±2 are observed and this result is shown to be consistent with photoionization selection rules in D_3h symmetry. Assignment of the threshold photoelectron spectrum results in an adiabatic ionization potential of 79 349 ± 3 cm^-1.
