## Abstract The barriers to internal rotation about the CN bond in several thiopiperidides have been determined by the NMR technique. It was found that the barrier height (Δ__G__^‡^) increases in the series cinnamoylthiopiperididem‐and __p__‐substituted cinnamoylthiopiperidides the barriers were s
The band shapes of the infrared fluorescence from the u= l-4 X '2 levels of CN isolated in rare gas matrices are investigated using a high-resolution Fourier-transform spectrometer. The spectra suggest nearly free rotation in solid Xe, with barriers to rotation increasing for the lighter rare gases.
