Spectroscopy and dynamics of jet-cooled 2-methoxynaphthalene

Autor: Michael R. Topp, Brian A. Pryor, Thomas Troxler

Publikováno v: Chemical Physics Letters. 274:71-78

The S1−S0 electronic transition of jet-cooled 2-methoxynaphthalene has been investigated by the use of laser-induced fluorescence, dispersed fluorescence and time-resolved emission spectroscopy. Two electronic origin transitions were observed, sepa
