FEMTOSECOND TEMPORAL SPECTROSCOPY AND DIRECT INVERSION TO THE POTENTIAL - APPLICATION TO IODINE

The use of femtosecond lasers in probing molecular dynamics is usually thought to yield improved temporal resolution, at the expense of spectral information. Here, we report on the use of femtosecond temporal spectroscopy (FTS) to yield accurate spectral information (vibrational and rotational) and to invert directly to the potential energy curve. As an example, we present the FTS analysis, inversion to the potential, and confirmatory wave packet calculations for the B 3Π0+u state of molecular iodine. © 1990.
