✦ Synopsis

Raman spectra of ethene adsorbed on "smooth" silver films and Ag( 111) surfaces are mode-selectively enhanced by postdeposition of silver at 40 K. Comparison with thermodesorption spectroscopy demonstrates that only the signal of C2H4 adsorbed at "defect sites" prepared by silver post-deposition is enhanced. This enhancement is short-range with respect to the adsorbate, but "long-range" with respect to the quantity of post-deposited silver.

## Abstract Surface‐enhanced Raman scattering (SERS) of 4‐hydroxybenzolc acid (4HBA) was investigated in a silver sol and at a silver electrode. The adsorption behaviour of 4HBA on the sol surface appeared different from that on the electrode surface. It was concluded that the molecule binds to the

## Surface -enhanced Raman spectra of 2,2 -bipyridine molecules adsorbed on rough silver surfaces were obtained. The spectra are interpreted in terms of two adsorbed species, one of which closely resembles the classical [Ag(bipy) 2 ] Y complex. The spectral features of the second adsorbate indicat
