I have a C- and a H-NMR spectrum. I know what all the peaks refers (all except for the aromatic carbons) to and which peaks goes to what carbon and adjacent hydrogen.

The only problem is that I have no idea on how to refer to the peaks. Is it okay to just write "Peak 3.794 and 3.7511 on the H-NMR spectrum is a doublet which refers to..."
Since I'm not certain of which peaks refers to what carbon in the aromatic, is it okay for me to say that peak 7.560 7.4510, 7.2945, 7.1883 are aromatic, or should I guess (I've never been a huge fan of writing guesses in reports).

Thanks in advance!

Typically you report peaks and their multiplicity (doublet, singlet, etc.) and then the number of hydrogens that they integrate to.

In my lab reports I usually put the information in a table (maybe this will be for the H NMR of ethyl acetate), something like:

Position (ppm)	Multiplicity	# of Hydrogens
1.25	Triplet	3
2.0	Singlet	3
4.1	Quartet	2

Typically
(CDCl3,ppm): 1,25 (t,J= xHz, 3H), 2.0 (s,3H), 4.1 (q, J=xHz, 2H)

Yes. Table form is very good for proton nmr. However, How about 13C NMR? since I am not the 13C NMR expert, how can I do in a table form? Also, multiplicity is always a singlet form. How about DEPT 45/DEPT 90/DEPT 135? How to do so?

Also, why is coupling constant all stated in proton nmr? Why is it important? It seems there is not relationship between the structure and coupling constant except oleic system, right?
