摘要：

H-2 NMR experiments in deuterated supercooled liquids are discussed in relation with alpha- and beta-relaxation heterogeneity with particular emphasis on the latter. The results are exemplified using data from deuterated ortho-terphenyl, propylene carbonate and toluene where partial deuteration provides additional information on intramolecular motion.
