Ultrafast Solvent-Assisted Electronic Level Crossing in 1-Naphthol

Ultrafast Solvent-Assisted Electronic Level Crossing in 1-Naphthol

Solvent effects: The nonadiabatic inversion dynamics of the energetic order of the electronic excited states of the photoacid 1‐naphthol have been revealed by ultrafast spectroscopy on a femtosecond timescale (see picture; IC=internal conversion). The energetic order of the excited states La and Lb...

Description
Summary:Solvent effects: The nonadiabatic inversion dynamics of the energetic order of the electronic excited states of the photoacid 1‐naphthol have been revealed by ultrafast spectroscopy on a femtosecond timescale (see picture; IC=internal conversion). The energetic order of the excited states La and Lb of 1‐naphthol is reversed in 60 fs in polar dimethyl sulfoxide solvent.
