Abstract
Thermal modulation spectroscopic techniques have been developed to study the optical properties of copper complexes of spermine and spermidine. Both pure and mixed solutions of the complexes were used to prepare films on special substrate heaters. Measurement techniques were developed to obtain approximately quantitative estimates of the composition of the mixed films from the modulation spectra. It is concluded that modulation spectroscopy is an appropriate tool for obtaining quantitative information on biologically important compounds. The spectra at 77 K and 300 K were significantly different.
