Abstract
The effect of a rigid nonpolar nonmesogenic solute "biphenyl," that is, C6H 5-C6H5 on the splay and bend elastic constants and on the rotational viscos ity coefficient of 4.4'-n-octyl-cyanobiphenyl is reported. The experiments involve the measurement of the voltage dependence of the capacitance of a c ell filled with the mixture. Anomalous behavior of both K-11 and Delta epsi lon near the N-S-A transition have been observed.
