**Abstract:**

*Abstract only given, substantially as follows. The frequency pulled 55Mn nuclear resonance in MnO at 4.2°K was observed as a function of the angle of rotation of the applied field H0 about a [111] direction. The resonance spectrum was found to consist of one branch, independent of the position of H0, and three other branches which coincide in frequency with the angle independent branch at 60° periods and move to lower frequencies at other positions of H0. These branches correspond to resonance in antiferromagnetic T-domains ordered along the four equivalent [111] directions. The components of H0 perpendicular to each of the [111] directions were calculated as a function of magnet angle*
