Photoacoustic spectroscopy was used as a technique to measure the visible spectra of powdery pharmaceutical samples. It was demonstrated that methyl red is in acid-form in crystalline cellulose and in baseform in MgO. This study indicates that photoacoustic spectroscopy is very effective in the analysis of pharmaceutical powders.
