Abstract
The use of a Guinier-Simon device has enabled us, firstly, to obtain t he XRD (X-Ray Diffraction) lines of three stoichiometric hydrates name ly NAT, NAD and NAM (Nitric Acid Trihydrate, Nitric Acid Dihydrate, Ni tric Acid Monohydrate) secondly, to detect the presence of these hydra tes in mixtures and also to determine their formation temperature. The latter information is essential to understand the mechanism of format ion of PSCs (Polar Stratospheric Clouds).
