摘要：
The Raman spectrum and SERS of glycine anhydride in acidic and basic media on positive silver colloids were recorded. Calculations of the vibration frequencies were performed for glycine anhydride by B3LYP at 6-31g(d) level. The assignment of Raman spectrum and SERS of glycine anhydride in acidic media were obtained with the help of calculation. It was found that the glycine anhydride is physically adsorbed on the surface of silver. The SERS of glycine anhydride is very different in acidic media from that in basic media. This seems to mean that the geometry of glycine anhydride on positive silver colloid in basic media has changed.
