The NO3 Frequency in Organic Nitrates

Abstract

THE characteristic inactive frequency at 9.5μ, corresponding to a wave-number shift of 1050 cm.-1, while it appears as a strong Raman line in the scattered spectrum of all inorganic nitrates examined both as crystals and in solutions, is not represented at all in the Raman effect of the organic nitrates. This is probably due to the influence of the CH group on the oscillations of the NO3 ion. However, in alcoholic solutions of these organic nitrates this line comes out significantly, the intensity of the line depending upon the solvent used and also upon the concentration of the solution.
