A study on the anisole-water complex by molecular beam-electronic spectroscopy and molecular mechanics calculations

An experimental and theoretical study is made on the anisole–water complex. It is the first van der Waals complex studied by high resolution electronic spectroscopy in which the water is seen acting as an acid. Vibronically and rotationally resolved electronic spectroscopy experiments and molecular mechanics calculations are used to elucidate the structure of the complex in the ground and first electronic excited state. Some internal dynamics in the system is revealed by high resolution spectroscopy.
