Experimental setup showing the essential components in stimulated Raman pumping and rotational Raman scattering. The time delay between the 683- and 954-nm pump beams and the 355-nm probe beam is variable from 15 ns–10 μs.
Rotational Raman spectra of the branch of plotted as a function of pump/probe delay time following the excitation to the state. The signals centered at 354.37, 587.09, 814.45, and represent Raman scattering from the states, respectively, while the additional peaks represent scattering from higher vibrational states.
Time traces of the populations of (a) the (circles) and (diamonds) states within the manifold, (b) the state, and (c) the state. The solid lines represent the simulated time dependence of these states as a result of vibrational energy transfer.
General rates and symmetry scaling parameters obtained from the energy-transfer model and scaled to represent a single molecule. These rates may be scaled appropriately to obtain the rate for any given vibrational energy-transfer process.
Comparison of vibrational energy-transfer rates from the state of obtained here to literature values. The reactions are written in terms of vibrational and rotational state.
