The photoconductivity and optical spectra of trapped electrons were measured at 77 K for glassy alcohols (methanol + 5% water, ethanol, 1-propanol, 1-butanol, and 2-propanol) and amines (diisopropylamine and 1,2-propanediamine). From comparison of both spectra, the optical spectrum has been assigned to bound-bound and bound-free transitions for all of the matrices studied. It has been found that excitation energies at the photoconductivity and optical absorption maxima are correlated with matrix polarity. Such a correlation has been interpreted in terms of a trapped-electron model.
