Abstract
An I2-vapor cell filter and an optical multichannel analyzer were used to investigate inelastic scattering with low-frequency shifts from a Ag electrode that is surface-enhanced Raman-scattering active. We have extended inelastic scattering measurements to ~0.5 cm−1 from the excitation frequency and have simultaneously monitored the spectral intensity from +60 to −60 cm−1. Attenuation measurements and the observation of I2-vapor absorption lines in the data verify that the observed signal is inelastic scattering and not the leakage of elastically scattered light.
