Hyperfine splitting (in MHz) of ro-vibrational levels of the HT⁺ molecular ion

Table 2. Hyperfine splitting (in MHz) of ro-vibrational levels of the HT⁺ molecular ion.

Abstract

We present systematic calculations of the leading order relativistic corrections for a wide range of rotational and vibrational states of the HT⁺ molecular ion. Finite size effects are also taken into account. These are the first complete ab initio calculations, which may be used for precision spectroscopy of the ro-vibrational spectrum in HT⁺.
