摘要：
A UV-vis absorption spectroscopy and surface-enhanced Raman scattering (SERS) study shows that benzyl mercaptan was found to be adsorbed faster than thiophenol on gold nanoparticle surfaces at a low bulk concentration of approximate to10(-7) M, whereas they appeared to exhibit almost identical spectral behaviors at high concentration of approximate to10(-5) M.
