Alignment media used for measuring residual dipolar couplings,
such as solutions of filamentous phages, phospholipid mixtures, polyacrylamide
gels and various lyotropic liquid crystalline systems were investigated with
respect to solvent effects on molecular structure. Structural parameters
of the small rigid model compound 13C-acetonitrile were calculated from dipolar
couplings and variations from expectation values were used for assessment
of solvent effects. Only minor solvent effects were observed for most of
the media employed and the measured structural data are in good agreement
with microwave data and theoretical predictions.
