Hyperfine-Resolved Rovibrational and Rotational Spectroscopy of OH${}^{+}$ ($X^3\hat{I}{\pounds }^{-}$)

Weslley G. D. P. Silva, Lea Schneider, Urs U. Graf +6

The OH${}^{+}$ ($X^3\hat{I}{\pounds }^{-}$) radical cation has been investigated by combining a 4 K 22-pole ion trap apparatus with high-resolution IR and THz radiation sources. Applying different typ…
