Abstract
The recently observed transient absorption of the lowest excited state of the special pair P at 2710 cm(-1) is assigned as a singlet which arises from the coupling of the two lowest triplets from the two dimer halves. INDO calculations are used to predict its intensity. The anal ogy of the coupling mechanism to the trip-doubler spectrum from P+ is shown and the influence of the double triplet on the Stark effect of P is investigated.
