A theory for the satellite peak in the NMR spectrum of rotating superfluid /sup 3/He--A is presented. Absorption at the frequency of the satellite is produced by spin waves localized on vortex lines. The peak frequency and total intensity of the satellite are calculated for both singular and nonsingular vortices: a comparison with the Helsinki NMR data strongly suggests that nonsingular vorticity was actually observed in the experiments.
