Complete Reconstruction of the Wavefunction of a Reacting Molecule by Four-Wave Mixing Spectroscopy
Abstract
Probing the real time dynamics of a reacting molecule remains one of the central challenges in chemistry. In this letter we show how the time-dependent wavefunction of an excited-state reacting molecule can be completely reconstructed from resonant coherent anti-Stokes Raman spectroscopy. The method assumes knowledge of the ground-state potential but not of any excited-state potential, although we show that the latter can be computed once the time-dependent excited-state wavefunction is known. The formulation applies to polyatomics as well as diatomics and to bound as well as dissociative excited potentials. We demonstrate the method on the Li molecule with its bound first excited-state, and on a model Li-like system with a dissociative excited state potential.
