Using time-resolved degenerate four-wave mixing, we have studied the pretransftional behavior of liquid crystal, MBBA, by measuring the temperature dependence of the molecular orientational relaxation time. The experimental result agrees fairly well with the theoretical prediction based on Landaude Gennes mode.
