Zusammenfassung

3-Hydroxyflavone (3-HF) and 3-deuteroxyflavone (3-DF) were examd. by fluorescence excitation spectroscopy in a supersonic free jet. Compared to 3-HF, vibronic bands of 3-DF are significantly narrower. Substitution of H by D also appears to split vibronic bands into at least three bands leading to a congested spectrum. Fluorescence-dip double-resonance spectroscopy revealed that the complicated ...
