In this poster we present details and background information on our spectroscopic analysis of the triplet ground state a3Σu+ and the first excited triplet state (1)3Σg+ of Rubidium 87 discussing its vibrational, rotational, hyperfine and Zeeman structure. This includes information that cannot be given in our talk "High resolution spectroscopy of Rb2 triplet molecules". In brief, we perform laser spectroscopy on ultracold Feshbach molecules to obtain precision data with a typical resolution of a few tens of MHz. With model Hamiltonians we can describe and understand the experimental spectra quite well. As a result we obtain optimized a3Σu+ and the X1Σg+ Born Oppenheimer potentials within a coupled channel model.
