| Abstract: | The ratio of intensity of one of the rotational lines in P branch to the total intensity of the R branch of a rotational vibrational band is shown to give' the temperature of the emission region. In the OH (7-2) band, intensity of (i) P1 (3) line, λ = 6922.8 Ǻ and (ii) Total R branch, λ = 6832 Ǻ is measured with the help of a photoelectric filter photometer with two narrow band filters. A third filter at 7115 Ǻ allows background measurements. Ratio of intensities of P1 (3) to total R branch is computed and compared with that calculated theoretically. The comparison gives the temperature. Preliminary results are presented. |
