Abstract

A method of detecting the presence of a given quadrupolar nucleus in a sample, the spin-lattice relaxation time of the nucleus varying with a given environmental parameter, comprising: determining a range of the spin-lattice relaxation time which corresponds to a selected range of the parameter; applying excitation to the sample to excite nuclear quadrupole resonance; and detecting the resonance response signal; the excitation being such that a detectable resonance response signal can be excited over the thus determined range of the spin-lattice relaxation time, and being such as to produce a flip angle of less than 45 degrees actual.
