 Title: A COMPREHENSIVE ANALYSIS OF THE ERRORS AFFECTING THE MEASUREMENT OF INTENSITIES IN INFRARED SPECTRA Creators: Rinsland, C. P.; Chen, Da-Wun; Rao, K. Narahari; Braun, W. C.; Fridovich, B. Issue Date: 1978 Publisher: Ohio State University Abstract: Problems encountered in the precise determination of line strengths are discussed. Physical sources of error are listed and described, along with suggestions for minimizing their effects. A mathematical analysis is given for the dependence of accuracy of line strength measurements on the accuracy of measurement for physical parameters relevant to the experiment. Numerical examples are presented for line strength measurements made for the $\nu_{3}$ - fundamental band of carbon dioxide at $4.3\,\mu$m. Finally a proposal is made for the use of $N_{2}O$ lines as standards for the calibration of line strength measurements and for intercomparison of data obtained at different laboratories. The main point to be recognized is that some intensity standards are very much in need.
