Emission Spectra of N2, O2, and NO Molecules Trapped in Solid Matrices

Abstract

Molecular systems are observed in emission in solid products from a gas discharge trapped at liquid helium temperature. Previous tentative molecular assignments have been checked with the help of isotopic substitutions of oxygen and nitrogen. The Herzberg system (A bands) of oxygen (A 3Σu+ — X 3Σg—) is analyzed and the molecular constants are derived for a molecule trapped in a nitrogen matrix. Another system (M bands) is attributed to the NO molecule (4II — X 2II).
