Abstract
The possibility of using the phase shift of the photoacoustic signal of different constituents of a composite sample for resolving the spectra of the constituents, at a fixed modulation frequency, is discussed. The proposed method is experimentally tested using samples of soda-lime–silica glass doped with binary oxide mixtures.
