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 L a and L b of 1‐naphthol is reversed in 60 fs in polar dimethyl sulfoxide solvent.
