✦ Synopsis

The field dependence of the 'H and 13C coalescence temperatnres 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 Tz relaxation times of the methyl protons show that Tz depends exponentially on temperature.

## Abstract The temperature dependence of the Debye‐Waller factors of vanadium and silicon in V~3~Si and that of the X‐ray Debye temperature are obtained from the integral intensities of X‐ray reflection measured at 11 temperatures ranging from 8 K to 293 K. It shown that the breaks on these curves
