The B phase of /sup 3/He in a magnetic field H has, in addition to the spin angular momentum Sapprox.H, an orbital angular momentum L/sub i/approx.R/sub i/kS/sub k/, where R/sub i/k is the rotational matrix entering into the order parameter of /sup 3/He-B ..delta..(T)R/sub i/ke/sup i/phi. A change in the energy of the fluid Omega-arrow-rightLapprox...cap omega../sub i/R/sub i/kH/sub k/ caused by the rotation of the vessel with angular velocity Omega-arrow-right has an orientating effect on the order parameter, comparable in magnitude to the orienting effect of vortices. It is proposed that the magnitude of L be measured from the shift of the NMR spectrum in rotating /sup 3/He-B.
