Abstract

Multichannel Raman spectroscopy utilizing a CCD detector is shown to be a sensitive technique for obtaining unenhanced Raman spectra of monolayer Langmuir-Blodgett films. Spectra of the C-H stretching region of cadmium stearate films with thicknesses from 1 to 27 layers reveal significant disruption of lateral packing and conformational disorder in the first few layers. Pretransitional disordering of the hydrocarbon tails is observed upon heating near to but below the melting point.
