Vibrational and vibronic processes in coherent 2D resonance Raman spectroscopy.
Coherent 2D resonance Raman spectroscopy is a multidimensional technique that is capable of separating and sorting peaks that appear heavily congested and disordered in conventional 1D spectra. It can sort rovibrational peaks according to rotational and vibrational quantum number, vibrational sequence, and rotational selection rule. New results suggest that pattern recognition methods can also be used to determine whether the highly detailed rovibrational information is coming from the ground electronic state or the excited electronic state. This capability is demonstrated using experimental results from I(2) and C(2).
