In this research the nuclear splitting level allowed energies are found for N+ in the NH3SO3 compound (sulfamic acid) when the angle between molecular axis and the axis of the applied magnetic field in the range. We noticed the splitting level by act
ing the strong magnetic field. Therefore, we calculated the contribution of electric quadruple in the splitting process and its average value was E0=-0.1987neV. Moreover, the splitting level energies were calculated at minimum and maximum spin values. In addition, we found the frequency difference Δω at each value of β-angle.
