Abstract: Raman Magnetic Resonance (RMR) spectroscopy for a heteronuclear AX3 spin system isrecorded by perturbing the highest-order quantum coherence state. The RMR experimentshows that an effective way for detecting higher-order quantum transitions is to prepare thehigher-order multiple quantum (MQ) coherence in the initial state. The product operatorformalism provides an exact method to predict arbitrary order MQ frequencies and intensitiesof RMR spectroscopy. By means of accumulation of Positive-negative alternate offset, thestrong single quantum signals are suppressed and hence the MQ transition signals can be detected with a higher efficiency.
