In our second work, we explore the near-threshold hyperfine structure of Cs2 molecules. While molecular states near the lowest energy manifold are well understood, an experimental and theoretical picture of the molecular states near the f1 = 3, f2 = 4 manifold is still lacking. We discuss the results of spectroscopy experiments mapping g-wave states in this new regime and compare our results to coupled-channel scattering calculations to extract quantum numbers. The states identified in this work introduce new possibilities in the study of coherent, many-body chemistry by enabling precise state control of BEC of Feshbach molecules in various quasibound rotational and hyperfine states.
