Abstract
Photoacoustic Spectroscopy (PAS) experiments in the visible and ultraviolet regions of the electromagnetic spectrum were carried out on a variety of tourmaline species. The results of our investigation show that PAS can be seen as a powerful alternative spectroscopic tool in the identification and characterization of color centers in mineral specimens.
