✦ Synopsis

A study of the transient photoexcited triplet of bacteriochlorophyll-a in a glass matrix at 60 K utilizing light modulation EPR spectroscopy is reported. In view of widely deviating results for the triplet sublevel depopulation rates, this problem was engaged via EPR lineshape analysis rather than direct kinetic measurements. This method also yields the relative population and spin-lattice relaxation rates.
