Coherent 2D Resonance Raman Spectroscopy as a tool for studying molecular structure

Coherent 2D Resonance Raman Spectroscopy (C2DRRS) is a new spectroscopic technique that can sort normally congested Resonance Raman peaks into predictable patterns. This paper discusses evidence that connects the location, shape and spacing of these patterns to the relative size of specific spectroscopic constants. Simulations and experimental results for the Δv = 0 and Δv = 1 transitions of the C2 Swan band reveal a relatively simple relationship between spectroscopic constants and the resulting 2D pattern.
