Spectra-structure correlations have been sought for each of the classes, with particular emphasis being placed on the 1600-1800 cm−1 region. The spectra in this region are often complex, reflecting subtle structural features in the condensed phases. Group frequencies for substituted succinimides, phthalimides, and maleimides are proposed.", pages = "812-817", url = "http://www.ingentaconnect.com/content/sas/sas/1990/00000044/00000005/art00009", doi = "doi:10.1366/0003702904087000", keyword = "Infrared, Molecular structure, Raman spectroscopy" }
