Abstract

A simple method is suggested for the preparation of pure nitrosonium nitrate (NO+ NO 3 ) thin films, by deposition of nitrogen dioxide from the gas phase onto a cold tip under specified conditions and subsequent warming up of the layer. Fourier-transform infrared spectra were used for its characterization and to determine its purity. The NO+ NO 3 solid thus formed was found to be stable up to 230 K. Raman examination of temperature cycling effects on thev(NO+) band and on the phonon region of the thin films indicates one amorphous and two crystalline phases. Amorphous-crystalline and crystalline-crystalline transition temperatures are reported.
