Beginner: Help understanding 3D NOESY

Beginner: Help understanding 3D NOESY

Hi, I am a person with a Computer Science background who is dealing with some NMR dataset. I am concerned with the assignment of NMR peaks from several experiments. For structure determination, I am dealing with 3D-NOESY data. I am finding it a little hard to comprehend what the several peaks mean here. I understand what the peaks in a 2D dataset like 1H-1H NOESY dataset mean but not on higher dimensions.

I do not understand the nomenclature followed in the naming of NOESY experiments because I feel a little lost in all the technical details in the text that discuss this. Can somebody help me understand what the experiment measures by looking at the name? One such experiment I deal with is 3D CCH-NOESY. Would there be a catalog that lists all such experiments?

Thanks!

The problem I faced is regarding the assignment of N15Edit NOESY and C13 Edit NOESY spectrum.I have already processed the fid data and converted to sparky ucsf format. Is there options available in sparky for auto peak picking, integration and assignment of my NOESY spectrum? And second query is regarding the generation of input files for structure calculation.
