Abstract
Photoacoustic spectra as well as optical absorption spectra were measured to study the heat generation by nonradiative processes in electrodeposited polyaniline films in the wavelength range of 310 to 800 nm. The shapes of both spectra depend on the pH for polymerization of electrodeposited polyaniline films. The shapes of infrared spectra also show the pH dependence. Photoacoustic spectra show that the changes of signal intensity are different from those of optical absorption spectra, suggesting the character of lattice relaxation of a low-dimensional system.Keywords
