摘要：

A mass-selected, partially rotationally resolved, resonant multiphoton ionization spectrum of the allyl radical, C3H5, is reported. Photoelectron spectroscopy, isotopic labeling, and rotational analysis establish that the band system corresponds to the C approximately [2(2)B1] <-- X approximately [1(2)A2] 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-degrees in the ground state to 117.5-degrees in the excited state.
