Abstract
The influence of applied electric fields on the pretransitional optica l activity (phi) in the chiral nematic 4-cyano-4-(2-methyl)butylphenyl (CB15) was investigated. A rotating analyzer system was used to measu re the optical activity and fields up to 800 kV/m were applied. The ze ro-field results are consistent with theoretical predictions and contr ibutions from the m = 2 mode to phi are evident in the data. Large ele ctric fields destroyed the contributions from the m = 2 mode.
