Potential Surface Properties and Dynamics from Molecular Spectra: A Time-Dependent Picture
In this article, a new point of view on the spectroscopic determination of potential surfaces is presented. The perspective is explicitly time dependent, although the theory given here is intended for interpretation of experiments in the frequency domain. We will travel back and forth between the time and frequency domains via Fourier transforms. Some of the characteristics of potential surfaces which we obtain are static ones, such as slopes and directions of excited (in absorption) or ground (in emission) potential surfaces in the Franck-Condon region. Other characterisitics are dynamic ones, involving certain decay and recurrence events which severely limit the form the potential surfaces may take but do not specify it completely.
