概要
- 論文の詳細を見る
By assuming an attractive potential between molecules which depends ontheir relative orientations and respective molecular configurations, the phasetransitions in the systena of flexible molecules are studied in a mean field approxi-nation. For simplicity, a two state model is adopted, where all configurations ofa molecule are simply classified into "long" and "short" cases. It is found thatthe orientational transition is accompanied with a certain change in the molecularconfiguration for the case of long and flexible molecules (type I), whereas with amuch smaller change in the case of short and rctther rigid molecules (type II).In the intermediate case, transitions of the typc I and II occur successively.Transitions observed in lipid tnembranes and in rnematogenic homologous seriescan be understood on the basis of these analyses.
