 note = {application/pdf, 学術雑誌論文, Crystal structures of 4-cyano-4'-alkylbiphenyls (nCB) and 4-cyano-4'-alkoxylbiphenyls (nOCB) show a different tendency: a remarkable even-odd effect for the former and dominant CN-CN interaction for the latter. In order to elucidate the difference between the two series, FT-IR spectra have been measured. CN stretching vibration frequencies for dilute solutions of CCl_4 (0.01 mol/l) are 0.5 cm^<-1> higher for nCB than for nOCB, giving a direct evidence of the different intramolecular interaction for isolated moleculeS. In mesophases, the frequencies on average are 1.0 cm^<-1> higher for nCB than for nOCB. Thus, the difference in mesophases (1.0 cm^<-1>) is larger than that for isolated molecules (0.5 cm^<-1>). Similar results were obtained for 4-cyanophenyl 4-alkoxybenzoates and 4-alkoxyphenyl 4-cyanobenzoates, showing the difference of intra- and intermolecular interactions due to the reversed directions of ester linkages with respect to the CN groups.},
