Doppler-free high resolution continuous wave optical UV-spectroscopy on the $\mathrm{A}{}^2{\Sigma }^{+}\leftarrow \mathrm{X}{}^2{\Pi }_{3/2}$ transition in nitric oxide

Abstract

We report on Doppler-free continuous-wave optical UV-spectroscopy resolving the hyperfine structure of the $\mathrm{A}{}^2{\Sigma }^{+}\leftarrow \mathrm{X}{}^2{\Pi }_{3/2}$ transition in nitric oxide for total angular momenta $J_X=1.5-19.5$ on the $\mathrm{o}{\mathrm{P}}_{12ee}$ branch. The resulting line splittings are compared to calculated splittings and fitted determining new values for the molecular constants $b,c,eQ{q}_0$ and $b_F$ for the $\mathrm{A}{}^2{\Sigma }^{+}$ state. The constants are in good agreement with values previously determined by quantum beat spectroscopy.
