报道了烯丙基自由基C{sub3}H{sub5}的质量选择、部分旋转分辨、共振多光子电离光谱。光电子能谱、同位素标记和旋转分析表明，该带系对应于C[2{sup2}B{sub1}]{L箭头}X[1{sup2}A{sub2}]跃迁，起始带位于248.15 nm。光谱模拟表明，自由基的平衡ccc键角从基态的124.6度降至激发态的117.5度。参考文献17，图2。
A mass-selected, partially rotationally resolved, resonant multiphoton ionization spectrum of the allyl radical, C{sub 3}H{sub 5}, is reported. Photoelectron spectroscopy, isotopic labeling, and rotational analysis establish that the band system corresponds to the C[2{sup 2}B{sub 1}]{l_arrow} X[1{sup 2}A{sub 2}] 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. 17 refs., 2 figs.
