"Tellurium vapor reacts with gaseous fluorine to produce a chemiluminescent flame. The emission in the visible and near infrared part of the spectrum of the flame has been previously attributed to the A2 psi - X 2 psi system of TeF. Excited TeF produced in the flame was investigated as a possible candidate for chemical lasing. This work was intended to further characterize the TeF flame using computer controlled simultaneous optical and mass spectroscopy. Assignment of some band head wavelengths in the TeF(A-X) system were checked and a mass spectrum of the flame was obtained. The mass spectrum revealed the presence of TeF, TeF2, TeF3, and TeF5 in the flame. The apparently complex chemistry and the distribution of chemical energy over several vibrational levels in excited TeF suggest that this flame is not a promising candidate for chemical laser development."--Abstract, report documentation page.

"This document was prepared by the Molecular Dynamics Division, Directorate of Chemical Sciences, Frank J. Seiler Research Laboratory, United States Air Force Academy, Colorado. The research was conducted under Project Work Unit Number 2303-F4-04, "Spectroscopic Investigations of the Group VI Halides". Lt Col Chester J. Dymek, Jr. was the Project Scientist in charge of the work."--Cover verso. "The work reported here represents the conclusion of a work unit whose objective was to investigate Group VI A fluorides formed in flames. The excited fluorides formed have potential as chemical laser active species. Part of the work was done as faculty research by Capt Moody who was on the Dept. of Chemistry faculty until being reassigned in June 1982. The programming and much of the experimental work was done as an Independent Study course project by CIC Joseph A. Menapace. ... This is the final report on this work unit."--Preface.
