“…Here again absolute intensity measurements are difficult because they are subject to large systematic uncertainties in the determination of the molecular concentration. The oscillator strengths determined by this method by Vanpee et al (1970) from flame emission and by Hooker k Main (1971) from shock-tube absorption are an order of magnitude shorter than the most recent values deduced from laser fluorescence. Other emission intensity measurements by Hebert k Tyte (1964) and by Tyte k Hebert (1964) as well as shock-tube studies by Linton k Nicholls (1969) were re-calibrated by Hebert et al (1980) using independently determined lifetimes (Johnson et al 1972;Dagdigian et al 1975); thus the concentration measurement problem was avoided and more reliable values could be obtained.…”

“…From the flame species composition given by Vanpee et aZ., 21 we calculated an A10 concentration of 5 x mole fraction, for an additive total mole fraction of A1 of 2.6 x This concentration would yield an f number of approximately 1 x…”

“…Jr., et 01., 1970, Nicholls R. W. and Pritchard, H. D., 1970, relative populations of excited electronic levels could be calculated from the ratio of observed spontaneous emission intensities, and compared with equilibrium values. 4) Relative vibrational level populations could be calculated from band intensity ratios, as described by Herzberg (1950), Vanpee, Kineyko, and Caruso (1970), Hebert and Tyte (1964), Naegeli (1967) and others. Separation of overlapping bands could be performed by the extrapolation technique described by Hebert and Tyte (1964) and Vanpee et 01.…”
