摘要：

Infrared and Raman spectra of betaine arsenate are recorded and analyzed. It is found that protonation of betaine occurs at the expense of proton from H3AsO4. Further, H2AsO4 and H3AsO4 groups coexist in the crystal. SERS spectrum is recorded in silver colloid. Chemisorbed arsenate species is found to have a C3V symmetry. Betaine arsenate molecule has two adsorption sites.
