dc.description.abstractPolarized Raman spectroscopy was used to investigate the development of orientational order and the degree of phase biaxiality in a bent-core mesogenic system. The values of the uniaxial order parameters < P-200 > and < P-400 >, and biaxial order parameters < P-220 >, < P-420 >, and < P-400 >, and their evolution with temperature were determined. The temperature dependence of almost all order parameters reveals a second order transition from the uniaxial to biaxial nematic phase with < P-220 > increasing to similar to 0.22 before a first order transition to the smectic-C phase, upon cooling.en_US
