title: Fast nuclear magnetic resonance correlation spectroscopy without diagonal peaks: the "2-1" correlation spectroscopy.
abstract: A fast NMR experiment is proposed for measuring correlation spectroscopy (COSY) spectra with diagonal peaks completely removed or largely suppressed. This new pulse sequence is based on double quantum spectroscopy but with delayed detection, so that the double quantum coherence is effectively transferred to single quantum coherence. Therefore, the pulse sequence can be named "2-1" COSY.
