Abstract
Dielectric properties of six bi-cyclohexyl phenyl compounds (3ccp-f, 3ccp-ff, 3ccp-fff, 5ccp-f, 5ccp-ff, 5ccp-fff) have been investigated. The compounds exhibit broad range of temperatures in nematic phase. Only one strong absorption process is observed in the absorption spectra; for clarity spectra only at some selected temperatures are presented. In each case relaxation frequencies are found to increase with temperature. The relaxation behavior is a result of Cole-Cole type process, the complex dielectric permittivity was fitted with the modified Cole-Cole equation to get the actual values of relaxation frequency (fc ) and symmetric distribution parameter (α).
