摘要： PROBLEM TO BE SOLVED: To provide a method of testing the nuclear quadrupole resonance of a sample containing quadrupolar nuclei and to discriminate a real nuclear quadrupole resonance response signal from the spurious signal brought about from the sample. SOLUTION: The method includes a step constituted so as to apply a pulse sequence, which contains at least one first pulse and one second pulse, to the sample to excite the nuclear quadrupole resonance and characterized in that the time between the first and second pulses is less than the length of the second pulse while the length of the second pulse is less than or equal to 0.5 times T 1p of the quadrupolar nuclei and the second pulse locks the magnetization formed by the first pulse at least partially and a step for detecting a response signal. The time between the first and second pulses and the length of the second pulse are made sufficient to attenuate the spurious signal due to the first pulse at least partially before the response signal detecting step.

摘要： PROBLEM TO BE SOLVED: To provide a method for conducting a nuclear quadrupole resonance test of a sample including a quadrupole nuclear, and distinguishing a true nuclear quadrupole resonance response signal from a spurious signal obtained from the sample. SOLUTION: The method includes: a step for applying a pulse sequence including at least a first single pulse and a second single pulse to the sample, and exciting nuclear quadrupole resonance; and a step for detecting the response signal. In the exciting step, a magnetization generated by the first pulse is partially locked by the second pulse. A duration between the first and second pulses is shorter than a length of the second pulse. The length of the second pulse is shorter than a half of T 1p of the quadrupole nuclear. The duration between the first and second pulses and the length of the second pulse are sufficient to partially attenuate the spurious signal before a step for detecting the spurious signal obtained from the first pulse.
