Multi-dimensional wavepacket and potential reconstruction by resonant coherent anti-Stokes Raman scattering: Application to H ₂O and HOD

We have recently proposed a methodology for reconstructing excited-state (ExS) molecular wavepackets, and the corresponding potential energy surface, from three-pulse resonant coherent anti-Stokes Raman scattering and knowledge of the ground-state potential [Avisar and Tannor, Phys. Rev. Lett. 106, 170405 (2011)10.1103/PhysRevLett.106.170405]. The methodology is general for polyatomics and applies to any form of ExS potential - bound or dissociative. In our previous work we demonstrated the method on diatomics. Here, we demonstrate the method on the triatomics H ₂O and HOD, reconstructing the ExS wavepacket and potential in the two bond-stretching coordinates.
