The unique amplitude obtained by an inversion of an observed Raman excitation profile is one of minimal phase. As the frequency varies, the phase of such an amplitude can span a range larger than 27r. Therefore such an inversion can yield an amplitude that accurately reproduces the input profile. It

โฆ Synopsis
The short-time dynamics of a nonstationary state is here determined by a direct inversion of an experimentally measurable Raman excitation profile. The procedure is based on the analytic properties of the Raman scattering amplitude and is best implemented within the maximum entropy formalism. A computational example for resonance Raman excitation profiles in the B state of iodobenzene is presented.
