摘要：
A detailed study of the Raman and infrared spectral line shapes and line parameters of aqueous solutions (both H2O and D2O) of AgNO3 is interpreted in terms of an equilibrium between "'free" ions and the ion pair Ag+NO3-. An association constant of 0.1 M-1 was obtained from both the 717 cm(-1) and 1047 cm(-1) line intensities. Spectral features suggest a significant degree of covalence in the interaction. A C-s(sigma(V)) model with Ag+ above the plane of NO3- is consistent with the data.
