Zusammenfassung
Spectral evolution of transient absorption and gain for 3-hydroxyflavone (3-HF) in dry methylcyclohexane and fluorescence excitation spectrum of deuterated compd. isolated in a supersonic jet are reported. A comparison suggests that jet spectroscopy interrogates a metastable isomer of 3-HF in the electronic ground state. Semiempirical calcns. support this hypothesis.
