Abstract

GRAPHICAL ABSTRACT: Abstract: Laser flash photolysis (LFP) time-resolved UV–VIS (TRUV) spectroscopy was carried out on the acetonitrile solution of triarylphosphines, Ar3 P, in an oxygen, air, or argon atmosphere. The transient absorption most likely from a triarylphosphine radical cation, Ar3 P ·+, appeared on the TRUV, which disappeared with the rate depending on the concentration of O2 .
