Query: Full molecular dynamics simulations of liquid water and carbon
  tetrachloride for two-dimensional Raman spectroscopy in the frequency domain   Frequency-domain two-dimensional Raman signals, which are equivalent to
coherent two-dimensional Raman scattering (COTRAS) signals, for liquid water
and carbon tetrachloride were calculated using an equilibrium-nonequilibrium
hybrid MD simulation algorithm. We elucidate mechanisms governing the 2D signal
profiles involving anharmonic mode-mode coupling and the nonlinearities of the
polarizability for the intermolecular and intramolecular vibrational modes. The
predicted signal profiles and intensities can be utilized to analyze recently
developed single-beam 2D spectra, whose signals are generated from a coherently
controlled pulse, allowing the single-beam measurement to be carried out more
efficiently.
