Spin-valley coupling

Three important conclusions emerge from this analysis. First of all, all INDOR responses induced by this particular mechanism will be in the negative direction, as they eifectively correspond to the trace of the valley between a pair of spin-tickled transitions. The second, and more important, conclusion is that INDOR responses will only be induced at frequencies corresponding to transitions that are spin-coupled to the transition that is being monitored no other transitions can induce INDOR responses. Thus, as the third conclusion, the INDOR experiment can be used to detect transitions that are entirely obscured by other overlapping transitions. ...
