Structural peculiarities of quench-condensed pure and argon-doped nitrous oxide

Abstract

Electron diffraction studies have been carried out for condensed N 2 O and N 2 O-Ar films. Deposition took place at substrate temperatures of 10 and 20 K. The growth process of N 2 O deposits was studied. A strong effect of argon impurities on the structure of the nitrous oxide matrix has been observed. The phase separation of the solutions was studied. The equilibrium solubility of argon atoms in nitrous oxide is very low. Introduction of a small amount of argon impurity into the molecular lattice destroyed the crystal structure. An effect of the size of the sample on its structure was also studied.

Structure of nitrous oxide-carbon dioxide alloys

“…Much is known about the effects of dilution of spherically symmetric atoms in a molecular crystal matrix. It has been established that the rare-gas doping lowers the potential barrier hindering the rotation of molecules [10,11]. The binary systems in which the both molecular components are substances with a strong anisotropic interaction between particles, have not investigated.…”
