Article abstract of DOI:10.1016/0022-2860(93)07964-X

The IR spectra of acetamide and some of its deuterated derivatives in argon matrices (14 K) have been obtained in the region 4000-200 cm^-1.An injection system was developed to avoid multiple site splitting.A normal coordinate analysis has been carried out for the a" vibrational modes and from the C NH2 torsional force constant the potential barrier was calculated to be 81 kJ mol^-1.
