Gas phase diagnostics with multispecies diatomic spectra is discussed.
Analyses of spectra from the A(3) Pi(i) <-> X-3 Sigma(-) system of NH
and the C-3 Pi(u) <-> B-3 Pi(g) second-positive system of N-2 are pre
sented. Multispecies spectroscopy is applied to experimental spectra o
btained from laser-induced breakdown plasmas in anhydrous ammonia gas
and a low-pressure discharge lamp. (C) 1998 Optical Society of America
