摘要:

Chemisorption and conformation of ω-mercaptoalkanols (HO(CH2)nSH, n=2, 6, 10) on silver mirror and HNO3etched silver foils have been observed by Fourier transform Surface Enhanced Raman Scattering spectroscopy (FT-SERS). The conformations of these adsorbates were affected by molecular chain length and surface roughness. In the adsorption state most of adsorbates inclined to be in trans conformation and ratio of trans to gauche conformation increased with the chain length.
