Explanation / Answer

In 13CNMR, the peaks normally coming is

The proton present in Methyl group or sp3 hbridized carbon contain hydrogen will come at 5-50

The carbon attached to Nitrogen and oxygen will come in the range 45 – 90

Anomeric and nitrile carbon will come in the range 90-120

Olefinic and aromatic proton will come in the range 120-140

Carboxylic acid, ester and amide carbon are present in the range 165-180

Aldehydes and ketone carbons are coming in the range 185-210.

In your spectra contain the sp3 hybridised carbon, carbon attached to nitrogen or oxygen, aromatic carbon and carboxylic acid carbon.

With only this 13CNMR, we can not draw the structure. it needs 1HNMR, IR and emrical formula or atleast 1HNMR and emprical formula.
