Webdipolar coupling NOESY is a correlation spectroscopy, where the transfer of magnetization among the spins is through dipolar coupling. NOESY spectrum resembles COSY and TOCSY with the presence of diagonal and cross peaks. However, the cross peaks represent the nuclei that are close in space rather than coupled with each other via bond.
