Paper Abstract

A mass-selected, partially rotationally resolved, resonant multiphoton ionization spectrum of the allyl radical, C3H5, is reported. Photoelectron spectroscopy, isotopic labelling, and rotational analysis establish that the band system corresponds to the 22B1 $IMP 12A2 transition, with an origin band at 248.15 nm. Spectral simulation indicates that the equilibrium CCC bond angle of the radical decreases from 124.6 degree(s) in the ground state to 117.5 degree(s) in the excited state.
