We have performed radio-frequency dissociation spectroscopy of weakly bound^6Li_2 Feshbach molecules using low-density samples of about 30 molecules in anoptical dipole trap. Combined with a high magnetic field stability this allowsus to resolve the discrete trap levels in the RF dissociation spectra. Thisnovel technique allows the binding energy of Feshbach molecules to bedetermined with unprecedented precision. We use these measurements as an inputfor a fit to the ^6Li scattering potential using coupled-channel calculations.From this new potential, we determine the pole positions of the broad ^6LiFeshbach resonances with an accuracy better than 7 \times 10^{-4} of theresonance widths. This eliminates the dominant uncertainty for currentprecision measurements of the equation of state of strongly interacting Fermigases. For example, our results imply a corrected value for the Bertschparameter \xi measured by Ku et al. [Science 335, 563 (2012)], which is \xi =0.370(5)(8).
