Spectroscopy of the Hyperfine Structure of HD${}^{+}$ in Rotationally Excited States with 10-ppb Uncertainty

D. Kliukin, V. Barbé, T. Klijn Velderman +5

We report the first measurement of the total hyperfine interval in the manifold of the ($v=0,L=3$) rovibrational state of HD${}^{+}$ using microwave spectroscopy of HD${}^{+}$ ions in a li…
