Notes:
The field dependence of the 1H and 13C coalescence temperatures in N,N-dimethyltrichloroacetamide has been used to determine the most reliable activation parameters for internal rotation of the amide moiety. The results were found to be in excellent agreement with those obtained earlier by the double-fitting procedure and demonstrate its validity. Direct measurements of the T2 relaxation times of the methyl protons show that T2 depends exponentially on temperature.
