Abstract

original image

How exciting! A combined experimental and theoretical study of the surface-enhanced hyper-Raman scattering (SEHRS) provides a detailed picture of the electronic excited state of the benchmark Rhodamine 6G molecule (see picture). These results demonstrate the ability of SEHRS to explore excited states that are not easily accessible via one-photon excitation using nonlinear spectroscopy at very low (10−10M) concentrations.
