Dissertation/Thesis Abstract

Near-infrared Spectroscopy of Diatomic Molecules: Analysis of a New Electronic Transitions in Molybdenum Monoxide and Zirconium Fluoride
by Harms, Jack C., M.S., Southern Illinois University at Edwardsville, 2014, 57; 1565498
Abstract (Summary)

Two diatomic molecules have been studied using electronic spectroscopy: molybdenum monoxide, MoO, and zirconium fluoride, ZrF. The (0,0) band of the c 3 Π1 - a 3Σ-0+ transition of MoO has been recorded in emission at high resolution. The MoO molecules were produced using a Mo hollow cathode sputter source with neon support gas and oxygen as the oxidant. The transition was assigned using isotopologue shifts and new ab initio calculations performed by Wenli Zou. The new transition and calculations led to the reassignment of previous research on MoO. The (1,1) band of the C 3/2 - X 2Δ3/2 transition of ZrF was recorded in high resolution using intracavity laser absorption spectroscopy. The ZrF molecules were produced with a zirconium-lined copper cathode sputter source with sulfur hexafluoride as the fluoride source. The transition was assigned using rotational branch structure and combination differences and bandhead predictions from a previous study by Martinez and Morse. The MoO transition was analyzed using PGOPHER, and ZrF was analyzed using an in-house least squares fitting program. Molecular constants and full analyses are presented.
