INFRARED ABSORPTION IN HEATED AIR FROM VIBRATION-ROTATION BANDS OF NITRIC OXIDE
Abstract
The contribution to the spectral absorption coefficient of heated air arising from the vibration-rotation bands of nitric oxide has been calculated with the aid of the SACHA digital computer programs. These band systems were theoretically reconstructed on a line-by-line basis using experimentally determined constants whenever these were available. A magnetic tape spectral atlas containing the reconstructed spectra was then employed by another computer program to calculate the average transmission of infrared radiation through a slab of heated NO whose occupation numbers were chosen to conform to the appropriate air case. Several parameters were varied in the calculation including the line half-width. Results of the calculations are contained in the form of graphs and tables. Computations were made for temperatures from 1000 K- 5000 K and for densities of normal atmospheric to 0.0001 normal. Frequencies covered were between 1200/cm and 10,000/cm (wavelength = 1 micron-8.3 micron).
