Threlfall, T. published the artcileThe infrared spectra of amides. Part 1. The stretching vibrations of primary carboxamides, SDS of cas: 79-07-2, the publication is Vibrational Spectroscopy (2022), 103386, database is CAplus.
The IR spectra of more than 150 primarycarboxamides in the NH stretching and the carbonyl region have been measured. Comparison is made with Bellamys anal. of the stretching modes of amines. The offset to higher frequencies of amides compared with amines is attributed to the widening of the bond angle. The sym. and antisym. stretching of the NH2 bonds is analyzed via a rearrangement of the Linnett equations. It is shown thereby that changes of bond strength vary the sym. and antisym. frequencies approx. proportionately while deviations from that relationship are due either to changes of the bond angle, steric hindrance or to hydrogen bonding. The spectral changes of m- and p-substituted amides are correlated with Hammett sigma functions, both in the carbonyl and the NH2 stretching region. Intensities and the influence of steric effects are also discussed.
