THE EMISSION SPECTRUM OF THE HYDROGEN-FLUORINE $FLAME^{*}$

Abstract

The emission spectrum of the hydrogen-fluorine flame has been photographed over the range 5,500-10,400 A with a 2-meter grating spectrograph. The 3-0, 4-1, 5-2, 4-0, 5-1, 6-2, 7-3, 5-0, 6-1, 7-2, 8-3, and 9-4 bands of hydrogen fluoride have been measured. For several bands levels above J=20 have been observed. These data have permitted improved molecular constants to be established.
