Molecular Orientation Measurements in Polymers by Infrared Spectral Subtraction

Volume 35, Number 4 (Aug. 1981) Page 432-435

Garton, A.; Carlsson, D.J.; Wiles, D.M.


The data manipulation ability of a Fourier transform IR spectrometer is exploited to characterize molecular orientation in polymers. In particular, the application of spectral subtraction to dichroic ratio determination and to the measurement of three-dimensional orientation via sample tilting and internal reflection spectroscopy is explored for nylon film samples.
