With reference to recent laser investigations of excited state reactions of maleic acid in Letokhov’s group, relevant excited state constants were determined by means of a physico-mathematical methods package of nonlinear absorption and the excited state populations were calculated for the experimental conditions. Based on this, a change of the assignment of the found reactions to excited states is suggested in the following manner: dimerization in T1 and maleic acid formation in a higher excited triplet.
