nuclear magnetic resonance pulse sequence spin echo pulse sequence A pulse cluster used in NMR experiments which manipulates signals such that, at the end of the sequence, the effects of chemical shift differences have been compensated/removed. Used most simply to compensate for inhomogeneities in the magnetic field but delays in the sequence also permit various possible manipulations of the magnetisation. For the pulse sequence see Phys. Rev., (1950), 80, pg 580. spin echo sequence CHMO:0001868 spin-echo sequence spin-echo pulse sequence 2009-05-29T12:00:00Z https://orcid.org/0000-0001-5985-7429
