Abstract

Spin cast and Langmuir-Blodgett thin films of atactic poly(methyl methacrylate) were studied by Fourier transform infrared spectroscopy, attenuated total reflection spectroscopy. The average molecular orientations of the films were found to remain unchanged upon annealing and also upon exposure to water. The absorbances of individual water bands were determined by detailed spectral analysis and compared with a one-dimensional Fickian model.
