Structure of Fluorine Supported Flames. III. Vibrational Disequilibrium of Third and Fourth Levels of HF in Dilute Low Pressure F2--F2 Flames,
Abstract
An experimental system has been designed and tested for the spectrophotometric study of low pressure fluorine supported flames. Fluorine gas flowrates of 5 to 500 cc/sec can be accurately measured and easily controlled. A multidiffusion burner and vacuum housing suitable for optical spectroscopic measurements is described. The continuously converting up to 40 cc/sec (at NTP) of gaseous F2 to CF4 with a total throughput of 25 l/sec. Low pressure hydrogen-fluorine flames diluted with argon have been stabilized under conditions suitable for measurement of both kinetic and relaxation processes. A total of 21 vibration-rotation bands of HF were observed. Temperature profiles of fluorine rich, lean and stoichiometric flames have been determined from the 3-0 emission band of HF. (Author)
