The rotator phase transitions in odd n-alkanes, n-C21H44 and n-C25H52, were investigated by optical microscopy. On cooling an n-C25H52 single crystal, a new transient intermediate state was observed within 1/30 s between the rotator phase (RV) and th

In a lamellar structure with a density-difference between crystalline and non-crystalline layers, a new method for simultaneous determinations of the degree of crystallinity and the density-difference is proposed. This method utilizes the temperature
