FIG. 1.

Rotationally resolved fluorescence excitation spectra near of the origin bands in the transitions of (a) bare indole at and (b) the indole–water complex at . and indicate the origins of the and subtorsional bands, respectively, in the complex spectrum.

The Stark effect in indole. Portion of the rotationally resolved spectrum of indole extracted from near the band origin (see Fig. 1) showing the large perturbations in the spectrum due to an applied electric field.

FIG. 3.

Illustration of indole showing its in-plane inertial axes and the orientations of its permanent electric dipole moments in the two electronic states.
