1H-13C COSY (HETCOR)

1H-13C COSY (HETCOR) 

1H-13C COSY is the heteronuclear correlation spectroscopy. The HETCOR spectrum is correlated 13C nuclei with directly attached protons. 1H-13C coupling is one bond. 
The cross peaks mean correlation between a proton and a carbon . If a line does not have cross peak, this means that this carbon atoms has no attached proton (e.g. a quaternary carbon atom)
