Abstract:

Spectral data for seventy-eight amides were recorded from 700 to 250cm, and analyzed for spectra-structure correlations. The information obtained can be used in identification of these compounds. The spectra were found to be very rich in absorption bands and thus they would be useful in fingerprint characterization when used in conjunction with the 4000 - 700cm region. Some new group frequencies were observed and their assignments are discussed and compared with assignments previously published. A comparison of the C-CO deformation frequencies of amides with that of acids, aldehydes and ketones is made. It is shown that this vibration gives rise to a good group frequency in all of these classes. Author
