✦ Synopsis

Amide-rotational barriers of a series of para-substituted N,N-dimethylbenzarnides and -cinnamamides have been obtained by both the intensity ratio method, according to Rogers and Woodbrey,* and an iterative total line shape analysis.

From a comparison of the results, it is concluded that a discussion of rotational barriers obtained with the intensity ratio method should preferably be based on AGSc values, which are nearly equal for both methods, rather than on AG: a t other temperatures. * Part 11, ref. 1 .
