4 DQF-COSY, Relayed-COSY, TOCSY Gerd Gemmecker 1999 Double-quantum filtered cOSY The phase problem of normal COsY can be circumvented by the dQF-COSY, using the MQc term generated by the second 90 pulse Ilz cos( @2t1) cos( t1) polarization
2 Basis Principles of FT NMR C Gerd Gemmecker 1999 Nuclei in magnetic fields Atomic nuclei are composed of nucleons, i.e., protons and neutrons. Each of these particles shows a property named\spin\(behaving like an angular momentum) that adds up to the total spin of the
