获得了环丙基碘在环己烷溶液中的共振拉曼光谱，其激发波长与A带吸收光谱有共振关系。这些光谱表明，Frank−区光解动力学具有多维特征，主要沿着名义C−I伸缩和名义C−C−I变形简正模运动，并伴随着沿着名义环丙环呼吸和环变形简正模的适度运动.进行了初步的共振拉曼强度分析，并将环丙基碘的结果与以前报道的几种环烷基碘和非环烷基碘的结果进行了比较。
Resonance Raman spectra were obtained for cyclopropyl iodide in cyclohexane solution with excitation wavelengths in resonance with the A-band absorption spectrum. These spectra indicate that the Franck−Condon region photodissociation dynamics have multidimensional character with motion mainly along the nominal C−I stretch and nominal C−C−I deformation normal modes accompanied by moderate motion along the nominal cyclopropyl ring breathing and ring deformation normal modes. A preliminary resonance Raman intensity analysis was done, and the results for cyclopropyl iodide were compared to previously reported results for several cyclic and noncyclic alkyl iodides.
