Precision spectroscopy with ultracold 87Rb2 triplet molecules

Abstract

In this thesis I report precision spectroscopy with ultracold 87Rb2 triplet molecules where we use lasers to couple the states in different molecular potentials. We study in detail the lowest triplet states of Rb2. These states are of great importance for transferring weakly bound molecules to the ro-vibrational triplet ground state via states of the excited potential. As most experiments start from molecules in their singlet ground state, the triplet states were hard to access via dipole transitions and remained largely unexplored. The measurements presented in this thesis are the first detailed study of diatomic 87Rb2 molecules in these states.
