Multi-dimensional wavepacket and potential reconstruction by resonant coherent anti-Stokes Raman scattering: application to H2O 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)]. 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(2)O and HOD, reconstructing the ExS wavepacket and potential in the two bond-stretching coordinates.
