摘要

~(35)C1NQR and ~1HNMR relaxation times (T_(1Q),T_(1H)) were measured in a hydrogen-bonded (chloranilic acid)-(l,3-diazine) 1:2 molecular complex in a temperature range of ca.100-300 K.NQR frequencies observed were explained by the monovalent (1-) ionic structure of chloranilic acid,implying partial H-transfer to diazine molecules.This H-transfer was shown to be dynamic by observing a single T_(1H) minimum at ca.120 K.Two new relaxation processes observed by NQR in high-temperature range,but undetected by NMR,were shown to be H-transfer motions between differently charged states of chloranilic acid molecules.
