Golden, B. M.

A scheme for selecting resonant frequencies for the analysis of gaseous air pollutants using long-path absorption of narrow-band infrared sources is presented. A computer search is conducted using existing spectrometric data to determine lines with minimum interference and maximum sensitivity. Results are given for the pollutants O/sub 3/, N/sub 2/O, CO, CH/sub 4/, and the non-polluting species, H/sub 2/O and CO/sub 2/. In addition, accurate absorption line half-widths of NO were determined using a conventional high resolution infrared spectrometer and modern data-taking procedures.
