R. Knudsen et al., A LOW-TEMPERATURE MATRIX-ISOLATION INFRARED STUDY OF ACETAMIDES .1. ACETAMIDE AND SOME DEUTERATED DERIVATIVES, Journal of molecular structure, 321(3), 1994, pp. 187-195
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'' vibrationa
l modes and from the C-NH2 torsional force constant the potential barr
ier was calculated to be 81 kJ mol-1.
