Abstract
The absorption spectrum of carbon tetrafluoride (CF4) gas thermally decomposed under equilibrium conditions in a graphite tube furnace shows the bands of CF2 at a temperature T≈1900°K and also the bands of CF at a temperature T≈2400°K. These results are in approximate agreement with thermodynamic calculations made by Potocki and Mann when the high value of 170 kcal/mole for the heat of sublimation of graphite and when f values of about 10−3 for both the CF2 and the CF bands are assumed.Keywords
