Chemiluminescent Reaction of Tellurium with Fluorine: The A 2pi sub i-X 2pi sub i and B 2Sigma(+)-X 2pi sub i Transitions

摘要

Te reacts with fluorine to give a strong chemiluminescence between 3800 and 8700 A. The emission spectrum contains both 2 sigma(+) - 2 pi sub i and 2 Pi sub i -2 Pi sub i systems. TeF emission bands are of the Hund's type (a) without spin forbidden intermultiplet crossing. Spin orbit coupling of the X 2 pi sub i state is -497/cm as determined from the 2 sigma (+)-2 pi sub i transition. Vibrational constants are reported for all states and compare favorably with those obtained from theory. Keywords: Tellurium; Fluorine; Chemiluminescence; Laser excitation.
