Abstract
The surface freezing effect of n-alkane has been studied by Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy. Samples used in the experiment were n-C50H102 (pentacontane) 2500 Angstrom thick film s evaporated on Cu substrate. An ordered structure has been observed a t a 1.3 degrees C higher temperature than the bulk melting point. Angl e resolved measurement has revealed that the molecular long axis of pe ntacontane in the surface freezing layer is almost perpendicular to th e surface.
