During a g09 tddft
calculation we obtain the all necessary information such as transition energy,
transition moment, oscillator strength and orbital composition. How can you
assign the transition as valence transition, charge transfer transition, Rydberg
transition. All higher energy transition accompanied by small oscillator
strength are Rydberg transition??? Broad transition are valence transition???
Any help or reference would be appreciable. By the way this is model system no
experimental data is available.
