Ag colloids were prepared by the microwave heating method. The UV‐visible spectrum and the transmission electron microscopy (TEM) were employed to characterize the Ag colloids. The surface‐enhanced Raman scattering (SERS) spectra of chloramphenicol (CAP) in Ag colloids were successfully recorded. The Raman spectra of CAP were recorded with good concordance comparing to the theoretical results calculated by the Gaussian'98 program. CAP molecules on the Ag surface are oriented tilted to the particle surface via C20‐O23, N‐O13, and N‐O23, which played an important role in the SERS effect. Copyright © 2009 John Wiley & Sons, Ltd.
