Frequency and time-resolved triply vibrationally enhanced four-wave mixing spectroscopy
We report a two-color frequency domain triply vibrationally enhanced (TRIVE) four-wave mixing (FWM) method that is fully resonant and provides coherent multidimensional vibrational spectra. Temporal and spectral discrimination allow control of the coherent interference of multiple pathways including isolation of a specific pathway and coherent control of the relative intensities of peaks in a 2D spectrum. The method is the coherent analogue to two-color pump-probe spectroscopy and allows the dissection of the individual pathways.
