The electron structure, absorption spectra of K1 and its 3-fluoro-, 3-fluorophenyl-substituted derivatives have been calculated using the PIDO and ESP methods. Detailed analysis of the electron structure of excited states and possible channels of photochemical reactions as well as stereoeffects appeared due to substitution allowed us to produce photostable lasing media efficient in the blue-green spectral region.
