Provisional Recommendations

Organic and Biomolecular Chemistry Division

Glossary of Terms Used in Photochemistry

The first edition of the Glossary of Terms Used in Photochemistry (“Glossary”) prepared for publication in the Commission of Photochemistry of the IUPAC Division of Organic Chemistry by S. E. Braslavsky and K. N. Houk was published in 1988 [Pure Appl. Chem. 60, 1055 -1106 (1988)] and has been incorporated in the Handbook of Organic Photochemistry and in Photochromism: Molecules and Systems.

The second edition of the “Glossary” prepared by Jan Verhoeven and published in 1996 [Pure Appl. Chem. 68, 2223 -2286 (1996)] corrected some minor mistakes in the first one and was expanded especially to incorporate terms related to (photoinduced) electron transfer processes. Major photochemistry and photobiology journals have since adopted the “Glossary” as a guideline.

This third edition incorporates revisions and enhances the “Glossary” introducing terms related to molecular anisotropy, the use of polarized ultraviolet, visible, or infrared radiation, and non -linear optical techniques, as well as the emerging field of computation of excited species. Some changes have been introduced in this “Glossary” regarding the terms related to radiation energy to make this collection fully compatible with internationally agreed upon terms.
