Precision Spectroscopy of Molecular Hydrogen Ions: Towards Frequency Metrology of Particle Masses
arXiv:physics/0612106 · doi:10.1007/978-3-540-75479-4_12
Abstract
We describe the current status of high-precision ab initio calculations of the spectra of molecular hydrogen ions (H_2^+ and HD^+) and of two experiments for vibrational spectroscopy. The perspectives for a comparison between theory and experiment at a level of 1 ppb are considered.
