Absorption spectra of NONH2 isomers and NO in liquid ammonia solution: possible implications for Jupiter

Abstract

Molar absorption coefficients of NONH₂ have been measured for bands at 285 nm, 365 nm and 550 nm, and the bands assigned to the tautomeric species HNNOH, NH₂NO and HNNHO respectively. Solutions of NO in liquid ammonia have an absorption band at 425 nm which is assigned to a charge transfer complex of NO with NH₃. It is suggested that coloured solutions of NONH₂ and NO in liquid ammonia may contribute to the colours observed in the atmosphere of Jupiter.
