Abstract
The infrared spectra of the metal complexes of 4-amino-3-pentene-2-one were measured from 4000 - 20 cm−1. The absorption bands were assigned by comparison to other similar molecules: The Cu(II) complex of 4-methylamino-3-pentene-2-one, and complexes of acetylacetone. Force constants for the molecules were calculated using the Axsm matrix method. The spectra were measured at 298oK and 77oK.
