please provide the chemical shift, splitting, how many protons in each peak, and calculate the J coupling constant for above spectrum.
The structure is
the 1H NMR was 400 MHz and solvent CDCl3.
chemical shift value for
doublet peak is the average value of the doublet peaks.

Write down problem number.
Provide formula, HDI value, and a complete, chemically correct
structure for each problem.
Assign signals in the 1H and 13C spectra to specific atoms,
identify structural units and/or functional groups.
Example:
Problem # 3
Formula: C8H8O2
HDI: 5
1H NMR: p-substituted Ar at 7.27-7.97 ppm, benzylic CH3 group at
2.42 ppm, COOH proton at 12.9 ppm
13C NMR: carbonyl C at 167.8 ppm (ester or acid), benzylic CH3
at 21.40 ppm, 4 remaining signals are Ar...
how I can write this data in mhz and find the coupling
constant for this data. basically I wanna know how I can write this
data in data summary. thank you so much for your help.
I don't have those values
can you please describe it with out those values
