Abstract
Quantum-chemical methods (PNDO) are used to consider the changes in the triplettriplet absorption spectra on substitution and H-bonding for coumarins and benzoxazinones in the range 200–800 nm. This defines the ways of optimum excitation (lamp or laser) and explains how the excitation technique affects the lasing performance. The results agree well with the few measurements and are correlated with the lasing characteristics.
