We have made simultaneous measurements of the longitudinal and transverse NMR frequencies of A3 in fields of the order of 30 G in a parallel plate geometry, defined by Mylar films 100 μm apart, so that l is well oriented perpendicular to the static magnetic field. Comparison of our measurements with the quadratic axial-state frequency relation indicates that the A phase is axial in the pressure range 22.6 to 29.3 bars.
