The theoretical development of a method called Selected-States Magnetic-Reson ance Spectroscopy (SSMRS) is presented. The approach uses the Stern-Gerlach interaction for periodic displacement of paramagnetic elements by a periodically variable magnetic-field gradient. Measurement is performed by the method of Elasto-Magnetic–Resonance Spectroscopy (EMRS). The implementation of the proposed method has promising potential in magnetic resonance (MR), including huge improvement in sensitivity, measurement of MR parameters for selected Zeeman states and investigation of microviscosity in a medium containing paramagnetic elements.
