Abstract
Detailed studies of the Raman and infrared line parameters of AgNO3−CH3CN systems ranging from dilute solutions to 9M are reported. A concentration quotient of 1.1M −1 was obtained for the formation of the Ag+NO −3 ion pair when C<4M. The complex appears to have point group Cs(σV) with Ag+ in a “roll-on” position. The Ag+ ion is solvated by four molecules of CH3CN; nitrate ion replaces three of these when bound to Ag+. When C>4M, multiple ion aggregates form in the solution. A low-frequency 110 cm−1 line is ascribed to librational motions of NO −3 , probably bound to Ag+.
