Abstract
Molecular resonance quantified: The resonance Raman spectrum of rhodamine 6G is obtained at 532 nm and the scattering cross-sections are quantified using resonance broadband stimulated Raman spectroscopy. Thus, the molecular resonance and surface-enhanced effects in SERRS are quantified for the first time. The surface enhancement is ∼107–108 in typical SERRS experiments.
