概要
- 論文の詳細を見る
The fluorescence excitation and fluorescence spectra of jet-cooled 3-chlorotropolone (3CTR-h) and 4-chlorotropolone (4CTR-h) were measured in the S_1-S_0 region. Several transitions of 3CTR-h have been identified in the region of 26403-26694cm^<-1>, whereas only the origin band has been detected at 26338cm^<-1> in 4CTR-h. No tunneling splitting was observed in the both spectra, suggesting that the hydroxylic proton is localized almost completely in one well of an asymmetric double-minimum potential function along the proton transfer coordinate. The vibronic structure in the fluorescence excitation spectrum of 4CTR-h is extremely different from that of 3CTR-h, which is ascribed to the change of the geometry in S_1 of 4CTR-h.
