摘要：

The ultraviolet absorption spectra of a series of lactams with ring sizes of 5, 6, 7, 8, 9, 10, 11, and 13 have been studied in both water and cyclohexane. Solvent shifts allowed a partial separation of the n-π* band from the π-π* band in cyclohexane and enabled an estimate of its position and intensity. The effects of the configuration of the peptide group as well as the conformation of the molecule on the absorption maxima and the intensities of the π-π* and n-π* bands are discussed.
