We have measured transverse NMR in 3He superfluid through a pressure range of 1 to 13 bar. A comparison of A and B-phase data is made through the NMR relations of Leggett, which serve as an indicator of the order-parameter structure of the A-phase. Deviation from these relations may indicate a continuous distortion of the traditional Anderson-Brinkman-Morel model toward the planar state. Our results are consistent with identification of the A-phase as the axial state.
