Abstract
The first overtone region of OH has been measured in emission from an oxyacetylene flame in the region of 1.6μ. The rotational structure in the P branch of the 2→0 band, from K=4 through K=19, of the 3→1 band, from K=4 through K=15, and of the 4→2 band, from K=4 through K=10, has been identified. For each K value there are four lines. These are resolved for values of K>7. From the intensities of the lines, a vibration‐rotation temperature has been determined. For the mixture of gases burned in this work with small flames, it was found that the ``temperature'' was 2600±100°K.
