Gas phase diagnostics with multispecies diatomic spectra is discussed. Analyses of spectra from the A3Π i ↔ X3Σ- system of NH and the C3Π u ↔ B3Π g second-positive system of N2 are presented. Multispecies spectroscopy is applied to experimental spectra obtained from laser-induced breakdown plasmas in anhydrous ammonia gas and a low-pressure discharge lamp.
