摘要：

Quadrupolar splittings in the H-2 NMR spectrum obtained from a sample with natural abundance H-2 isotope are shown to be considerably different from those obtained from specifically deuteriated samples in an example of 4'-propyl-3-(3,4-difluorophenyl)bicyclohexane. The result indicates that the molecular ordering may be altered significantly by selective deuteriation, and shows the importance of natural abundance H-2 measurement in liquid crystal studies.
