Nitric Oxide Measurement Study: Volume I. Optical Calibration

Calibration devices suitable for providing known amounts of nitric oxide (NO) at temperatures ranging from 300 K to 2000 K and pressures of 0.5 atm (50.7kPa) to 2.0 atm (203kPa) are described with their design considerations. Methods for confirming nitric oxide concentrations are given. The spectroscopic theory for the absorption of ultraviolet radiation in the gamma (0,0) band of nitric oxide is reviewed. Experimental values for oxcillator strengths and broadening parameters for NO with various collision partners are provided. Experimental results confirming the adequacy of a computer spectral model and, hence, the calibration are presented along with the details of the model. Finally, the results of an empirical calibration of an infrared gas correlation spectrometer are given. (Author)
