where superscripts in the Hamiltonian elements represent the strongly-coupled TD1 state with a large J, the thermally activated TD2 state with the intermediate coupling, and the de-coupled T+D state, respectively. From eq. ( ), TD1 states are diagonalized using 𝑯 - and 𝜃 ) by the conformation dynamics in Fig. , the off-diagonal terms of HQmsDm and HDmQms are created to occur instantaneous coherences (rQmsDm and rDmQms), so that the spin polarization of
