- 中文摘要: In a heteronuclear spin system, with initially prepared single quantum (SQ) coherence of X-spin, the irradiation of the proton spins will induce all the possible transitions including those SQs and multiple quanta (MQs) available in the system to be studied. The MQs appear in a rather weak irradiation while a strong irradiation results in a complete decoupling situation. Theoretical analysis is made to explain this phenomenon and is agreed qualitatively with experiments in the CH/sub 2/ group. This phenomenon of MQ induction may happen in a decoupling experiment when the effective irradiation strength is rather weak and it may also provide a convenient approach to create and then to manipulate MQ coherences in heteronuclear spin systems.
