Abstract

IR and polarized Raman spectra of CH₃NH₃NaSeO₄ · 6H₂O (MASS), NaNH₄SeO₄ · 2H₂O (SAS), and their deuterated analogues are recorded and analyzed. In both the crystal symmetry of SeO^2-₄ is lower than T_d. The symmetry of CH₃NH⁺₃ is lower than C_3v and hydrogen bonding is strong in MASS. NH⁺₄ is not rotating freely in the crystal lattice of SAS. SERS spectra are recorded in two types of silver colloids. Colloid 1 adsorbs MASS through the nitrogen atom of CH₃NH₃ group. There are two different adsorption sites for MASS in colloid 2. SAS is chemisorbed by colloid 2 through the oxygen atom of SeO^2-₄. Shifting and splitting observed for the internal modes of SeO^2-₄ on adsorption are due to the reduced local symmetry of the ion.
