Abstract:
Apparatus and experimental techniques used in the measurement of the total absorptance of the ammonia bands near 950, 1628 and 3300cm are described. The total absorptances of these bands at 25C were measured for pure samples of ammonia and for ammonia mixed with nitrogen. The results are displayed graphically with total absorptance shown as a function of absorber concentration and equivalent pressure, which depends upon the partial pressures of the two gases. The experimental values of partial pressure, total pressure and total absorptance are tabulated and tracings of many of the spectra are shown. Values for intensity are given for each region studied. The equivalent pressure is expressed as a function of the self-broadening coefficient, which is related by simple kinetic theory to the ratio of the optical collision diameters. These derived ratios are listed. Author
