摘要: Abstract The half-width temperature dependence of various IR bands from the homologous series p -azoxyanisole in crystal, nematic crystal and isotropic liquid phases is investigated. preorientation potential barrier U OR determined. , on number carbon atoms alkyl chain shows an even-odd effect. A relationship between value mesophase stability was found.
