Determination of a set of fundamental constants from molecular hydrogen ion spectroscopy: a modeling study

J. -Ph Karr, S. Schiller, V. I. Korobov +1

The rovibrational transition frequencies of molecular hydrogen ions (MHI) can be accurately computed using ab initio nonrelativistic quantum electrodynamics. A subset of the fundam…
