Abstract
We present high resolution zero kinetic energy photoelectron spectra of the allyl radical through various intermediate vibronic states. The spectra yi eld an ionization energy of 65 762 cm(-1), corresponding to 8.153 eV, as we ll as frequencies for a number of cationic vibrational states. The spectrum from the B 0(0)(0) state shows activity in modes corresponding to out-of-p lane motion of the terminal -CH2 groups. This confirms the nonplanar geomet ry of this state suggested previously, and thus provides additional insight into the vibronic couplings in the intermediate states.
