The effect of confined one-gluon-exchange potential and instanton-induced interaction potential in the singlet (1S0) and triplet (3S1) channels for nucleon–nucleon interaction has been investigated in the framework of the relativistic harmonic model using the resonating group method in the adiabatic limit with the Born–Oppenheimer approximation. The contributions of the different components of the interaction potentials have been analyzed.
