A method of gyromagnetic resonance spectroscopy is disclosed which simplifies the resultant spectra by eliminating spin-spin coupling effects. The method is particularly useful for eliminating homonuclear spin-spin coupling effects. In the method, spin echo resonance of the resonators is obtained and...http://www.google.fr/patents/US4068161?utm_source=gb-gplus-shareBrevet US4068161 - Gyromagnetic resonance spectroscopy employing spin echo spin-spin decoupling and two-dimensional spreading
