Alkali Metal Emitters. 1. Analysis of Visible Spectra
Abstract
Visible spectra of flares containing magnesium as a fuel and lithium, sodium, potassium, rubidium and cesium nitrates as the oxidizers are presented. Atomic and molecular emissions are identified and assigned to electronic transitions. The emission characteristics of the atomic emitters are the same as those observed in other studies. Several emission bands, possibly from diatomic alkali metal species, are observed and tentatively assigned. The intensity of the 518 nm magnesium line is seen to decrease by two orders of magnitude when the oxidizer is changed from lithium nitrate to cesium nitrate. This change could not be easily explained on the basis of calculated equilibrium temperatures and species concentration.
