The surface-enhanced Raman scattering spectrum (SERS) of pyridine adsorbed on Ag20 clusters at room temperature is calculated by Jen-Ping Su, Yung-Ting Lee, Shao-Yu Lu, and Jyh Shing Lin on page 2806. They perform ab initio molecular dynamics simulations in connection with a Fourier transform of the polarizability autocorrelation function to investigate the static chemical enhancement behind the SERS spectrum. At a finite temperature, the enhanced vibrational modes of pyridine can be assigned through visual identification by using a new analytical scheme, that is, the single-frequency-pass filter (SFPF).
