Visible spectra of flares containing magnesium as a fuel and sodium nitrate, potassium nitrate and rubidium nitrate as oxidizers are examined for molecular emission from species such as diatomic alkali metals, alkali metal-magnesium diatomics and quasi-molecules such as Na-N2. Atmoic and molecular emissions are identified and assigned to electronic transitions. Emission characteristics of the atomic emitters are the same as those observed in other studies. Emission bands from diatomic sodium, diatomic potassium and diatomic rubidium are identified. Emission from a sodium-magnesium interaction is also observed. Assignments are made for the electronic states and transitions which give rise to these emitters. The nature of these interactions is discussed. Author
