We present measurements of the binding energies of 6Li p-wave Feshbach molecules formed in combinations of the |F=1/2,mF=+1/2⟩ (|1⟩) and |F=1/2,mF=−1/2⟩ (|2⟩) states. The binding energies scale linearly with magnetic field detuning for all three resonances. The relative molecular magnetic moments are found to be 113±7 μK/G, 111±6 μK/G, and 118±8 μK/G for the |1⟩-|1⟩, |1⟩-|2⟩, and |2⟩-|2⟩ resonances, respectively, in good agreement with theoretical predictions. Closed-channel amplitudes and the size of the p-wave molecules are obtained theoretically from full closed-coupled calculations.
