In this work, the novel theoretical approach to predict the torque for spin is studied. This approach is based on the novel quantities, the spin torque and the zeta force, which are proposed by one of the authors. These quantities govern the dynamics of the spin of electrons, and hence, can clarify the essential description of the dynamics of the electron spin. This approach would be applicable to many spin phenomena. In this work, as a first step of the demonstration of this approach, we investigate the spin torque and the zeta force of the dimers of alkali atoms, lithium, sodium, potassium, and rubidium.
