Spectroscopic Identification of the Nitronium Ion

Nature volume 158, pages 480–481 (1946)Cite this article

Abstract

EXTENSIVE studies of the Raman spectra of mixtures of nitric and sulphuric acids have been made by Chédin1. He showed that such spectra were characterized by the appearance of two prominent, polarized lines, at 1,050 and 1,400 cm.â1, which did not belong to the spectrum of either the nitric acid or the sulphuric acid molecule. The same two lines appeared if he added either nitrogen pentoxide or phosphorus pentoxide to pure nitric acid. He therefore assigned these lines to nitrogen pentoxide; but, since solutions of this substance in organic solvents gave a different Raman spectrum, he supposed that the nitrogen pentoxide, when in solution in nitric or sulphuric acid, exists in some special form.
