摘要：

The analysis of the Raman and FTIR spectra of sulfamic acid suggest a structure between that of zwitterion and molecular form. SERS spectra have been analyzed in two types of silver colloids. As S - O ..... Ag linkages are formed in one colloid, S = 0 fundamentals are enhanced in intensity and shifted in frequency. Appearance of a delta SOH band indicates the retention of SOH bonds in the metal-molecule adsorbed system. Further, splitting of the fundamentals, which arises from the lowering of the symmetry of the molecule on adsorption, is noticed. In the second colloid, the nu S-O band is shifted in frequency and enhanced in intensity. No band corresponding to delta SOH is noticed, indicating the removal of protons and formation of S-O ..... Ag linkages. (C) 1995 Academic Press, Inc.
