Abstract: The photochemical reaction of dichromated gelatin was studied by laser photoa-coustic spectroscopy,Results show that the solid-state reaction of the dichromate withgelatin obeys Watanabe-Westheimer reaction scheme. The photosensitivity of dichromatedgelatin is dependent on pH and concentration of dichromate solution.

Key words: dichromated gelatin, photochemical reaction, laser photoacoustic spectrum
