Abstract
The absorption spectrum of the $^{14}NO$ and $^{15}NO$ isotopomers of nitric oxide in the far-infrared has been measured and analyzed. Pure rotational transitions up to $J^{\prime\prime} = 37-1/2$ within the $^{2}\Pi_{1/2}$ and $^{2}\Pi_{3/2}$ spin components and several $^{2}\Pi_{3/2}\leftarrow ^{2}\Pi_{1/2}$ fine-structure transitions were recorded within the ground vibrational state. A least-squares fit to these data combined with lambda-doubling transitions measured by previous workers has resulted in significant improvement in the accuracy of the rotational and fine-structure parameters of these two isotopomers. Improved values for the lambda-doubling and hyperfine constants will also be reported.
