Abstract

The temperature and frequency dependencies of the proton spin relaxation in methyl naph-thalenes discussed in a preceding paper can be described quantitatively by assuming a rotatory jump model of the methyl groups in connection with a Cole-Davidson distribution of jumping times. The observed activation barriers are derived in good approximation from a Buckingham potential.
