Abstract
We have observed molecular resonances corresponding to every rovibrational level in 88Sr2 with a binding energy less than 8.5 GHz and rotational angular momentum J ≤ 4 (except for those occupying the 0 g potential, which remain to be observed). Nearly every measurement is made with sub-percent level accuracy, with certain measurements considerably more accurate. A complete table listing these levels is presented for the first time in this thesis.
Additionally, a thorough discussion of the techniques used to record the positions of these levels is presented. Lineshapes associated with the common technique of photoassociation spectroscopy are discussed in great detail and compared to those associated with the less common photodissociation spectroscopy. Careful evaluations of systematic effects are performed for a selection of levels to illustrate the capabilities and limitations of our experiment. Molecule-light coherence times approaching 10 ms are demonstrated, paving the way for future molecular clock studies.
