Abstract
The high field1H,19F, and13C NMR spectra of haloperidol (HP) in CDCl3 solution were recorded and analyzed with the aid of both homonuclear (H, H-COSY, H, H-COSYLR) and heteronuclear (H,C-COSY) chemical shift correlation experiments. Through space interactions between (1) the piperidine ring and the chlorinated phenyl ring and (2) the fluorinated phenyl ring and a methylene group were identified using phase sensitive Nuclear Overhauser and Exchange Spectroscopy (NOESY). The NOESY results are consistent with a planar structure rather than a folded version of haloperidol.
