WebSince the trace of D is zero, calculation of the energy state for a system with S = 1 requires only two independent parameters which are designated D and E. The spin coupling is direct in the case of organic molecules in the triplet state and biradicals, but occurs through the orbital angular momentum in the case of transition metal ions. WebThe principal mechanism for J-coupling is through bond polarization, but there are situations where a through-space effect seems to be operative. These occur in molecules where spin 1/2 nuclei are forced into close proximity. For example, in the compounds below, there is a substantial H - F J coupling even though the H and F d\u0027angelo live at the jazz cafe
