1. The infrared and Raman spectra of cis- and trans-hexatriene were remeasured and reassigned. Past assignment(s) were shown to be slightly, but significantly, in error. 2. The lower Rydberg transitions of cis-hexatriene were studied in detail. Firm assignments were obtained for the 3p(A1) and 3d(A2) Rydberg states. The 3s, 3p-prime, 3d-prime and 4s states were also observed. 3. A synthesis of the effect of different types of substitutional perturbations on the lower Rydberg spectra of conjugated polyenes was constructed.

1.测量了顺式和反式己三烯的红外光谱和拉曼光谱 重新测量和重新分配。 过去的任务显示出轻微， 但很明显是错误的 2.详细研究了顺式己三烯的低里德堡跃迁。 得到了3 p（A1）和3d（A2）里德堡态的可靠分配。 还观察到了3s、3 p-素数、3d-素数和4s态。 3.不同类型取代基效应的综合 对共轭多烯的低里德堡光谱的扰动， 构建了
