I need help with analyzing this two spectrums. Here is the list of possibilities of the compound

Stearic acid, benzophenone, biphenyl, or vanillin.

Number each hydrogen and carbon atoms for that assignment, and include the corresponding number in the NMR spectra. Include also the main FTIR bands and the assignment.

What the “fingerprint” signals in NMR and FTIR that allowed the characterization of the unknown are, discuss the most relevant crosspeaks in the COSY and HSQC experiments that helped with the identification, and compare your spectroscopic results
