Bands due to overtone and combination vibrational modes attributable to the imide grouping have been elucidated in the near-IR absorption spectra of small-ring cyclic imides, in which the grouping is in a c/s, ct~ conformation. The spectra closely parallel the spectra of c/s lactams except that two
