Use of a photoreversible fulgide as an actinometer in one- and two-laser experiments

Abstract

The photoreversible fulgide Aberchrome-540 has been tested and developed as an actinometer for one- and two-laser experiments. In the former, the technique allows the determination of extinction coefficients for short-lived reaction intermediates by a method that requires substantially fewer assumptions than other techniques in the literature. In the case of stepwise two-photon processes, the Aberchrome-540 method allows the determination of quantum yields for photoreactions of short-lived reaction intermediates. For this particular application the technique is the only one of its kind.Peer reviewed: NoNRC publication: Ye
