Methyl rotation in NMP-TCNQ - Butler, M.A.; Wudl, F.; Soos, Z.G. (Elsevier)
Comparisons of continuous wave NMR in NMP-TCNQ and the analog in which the methyl group is deuterated are used to show that methyl reorientation occurs in NMP-TCNQ at all temperatures (T 〉 1.5^oK). Methyl reorientation is suggested to contribute to the nuclear spin-lattice relaxation, and its effects on the specific heat are discussed.
