Part A. Vibronic transitions of rhodium monoxide (Rh¹⁶O and Rh¹⁸O) were observed in
the 380 to 700 nm region. Laser-induced fluorescence identified two ²[pi]r - X⁴Σ⁻ progressions
with origins at {15 667, 15 976} and {15 874, 16 167} cm⁻¹. These progressions
were labeled [15.8] ²[pi] - X⁴Σ⁻ and [16.0] ²[pi] - X⁴Σ⁻, respectively. Vibrational parameters
were determined for the ground and excited states...
Part B. Density functional and configuration interaction calculations on the lowest singlet
and triplet potential energy surfaces of hydrogen, fluorine, and chlorine azide for the
reactions XN₃ (~X¹A¹) -- NX(X³Σ; a¹Δ) + N₂ (X¹Σ⁺g) and XN₃ -- X(X²S; X²P₃/₂) +
N₃(X²[pi]g) (X = H, F, Cl) show that the lowest energy dissociation pathway proceeds exothermically to NX(a) + N₂ . This surface is crossed on the bound singlet region by a dissociative
triplet surface. Unimolecular decomposition rates for each pathway and the
branching ratio support the experimental observations: HN₃ dissociates to ground state
products while FN₃ and CIN₃ produce significant amounts of electronically excited NX. / Graduate
