| Research Abstract |
In order to investigate the surface selectivity of absorption sensitive SPR spectroscopy, spectra of oriented samples : uniaxially stretched polyethylene (PE) films and Langmuir-Blodgett (LB) films, whose main chains respectively have parallel and perpendicular directions to the internal reflection surface, were measured. According to the wagging mode, which is a vibration along to the alkyl chain, it is confirmed that absorption sensitive SPR spectroscopy is specialized for detection of out of plain modes as RAS measurement and more highly sensitive due to conditions for surface plasmon resonance.
