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 nonpolluting species, H/sub 2/O and CO/sub 2/. (auth)
