INTENSITY MEASUREMENTS AND ROTATIONAL INTENSITY DISTRIBUTION FOR OXYGEN A-BAND

Quantitative measurements of intensities and half-widths have been made for individual rotational lines of the atmospheric oxygen A-band. The total band intensity, as derived from the line intensity measurements, is 532 cm-1 km-1 atm-1 STP. The line half-widths at half intensity were determined by two methods for the PQ and PP branch lines and are found to vary from about 0.05 cm-1 atm-1 near the origin to 0.04 cm-1 atm-1 for high K″ values. The rotational intensity distribution is demonstrated to conform more closely to the theoretical Hönl-London factors calculated by either Schlapp or by Watson rather than those found experimentally by Childs and Mecke. © 1969.
