ABSTRACT:
NMR signals of low concentration solutes are obtained with suppression of NMR signal of solvent by sequentially applying a first RF pulse sequence, a 180.degree. RF pulse and a second RF pulse sequence to an object. Each of the first and second RF pulse sequence includes equally spaced RF pulses which have flip angles in accordance with binominal coefficients. Phase errors due to inhomogeneity of a static magnetic field are cancelled through the two-time application of equally spaced RF pulse sequence.
