HIGH RESOLUTION SPECTRUM OF THE 1,2-DIMETHOXYBENZENE/D₂O COMPLEX .

JOHN YI AND DAVID W. PRATT, Department of Chemistry, University of Pittsburgh, Pittsburgh PA 15260.

The rotationally resolved S₁ leftarrow S₀ electronic spectrum of the 1,2-dimethoxybenzene/D₂O complex has been analyzed. The D₂O complex appears 126 cm^-1 to the blue of the bare molecule origin. The complex spectrum exhibits two subbands separated by 45 MHz. These spectra have an intensity ratio of 2 to 1, with the stronger band shifted to lower frequency. Possible motions of the water molecule that are suggested by these data will be discussed.
