Abstract
This dissertation presents detailed studies of the electronic structures of two molecular systems, iron monocarbide (FeC) and rhenium mononitride (ReN). There had been no research on either molecule prior to the present investigation.
FeC is the first 3d transition metal carbide to have been characterized spectroscopically. The ground electronic state of FeC has been established in our studies to be an inverted ³Δ (³δσ¹) state, based on the experimental observations and molecular orbital considerations. Laser-induced-fiuorescence signals originating from the two lowest spin components of the ground X³Δ₁ state were observed. Investigation of the excitation spectrum of the molecule revealed two ³Δ₃ states and two ³Δ₂ states. A strongly perturbed band at 448nm was also rotationally analyzed and deperturbed. It involves three vibronic states with Ω=3....
