Molecular Studies of Gaseous Oxides.

Abstract

A surplus high temperature mass spectrometer has been successfully refurbished and put into operation. Preliminary measurements of the dissociation energy of gaseous praeseodymium monoxides gave the value of 175.9 + or - 3 kcal/mol (or 7.65 + or - 0.13 eV). Final analysis of the results on the dissociation energy of gaseous europium monoxide gave the value of 111.9 + or - 2.4 kcal/mol (or 4.85 + or - 0.10 eV). Preliminary measurements on the vacuum ultraviolet spectra of molecules formed with mixtures of argon + oxygen and of krypton + oxygen have been performed. In the case of Kr + O2 five continua with peaks at 1490A, 1830A, 2090A, 2320A, and 2520A, are observed. (Author)
