Abstract: The properties of correlation functions between spins in a specific spin model with no frustration, and with high frustration are compared. It was already confirmed that the ground state formation of our no frustration model showed two-state Arrhenius-like kinetics, such as observed in protein folding. In this paper, we present that the correlation functions of the non-frustration system are characterized by spin motions of the lowest eigenvalue mode, defined by the interspin interactions near the transition temperature. The Arrhenius kinetics are regarded as the transition between this and the ground states, and thus our result denotes the implication to the protein folding mechanism.
