$^{1} H$ $""^1H$ $NMR spectroscopy$ $"NMR spectroscopy"$ would probably be the best bet.

Explanation:

Aromatic protons, or at least aryl protons belonging to $C_{6} H_{6}$ $C_6H_6$ or $C_{6} H_{5} X$ $C_6H_5X$ rings, etc. would probably be best identified by their $^{1} H$ $""^1H$ $NMR$ $"NMR"$ spectrum. These occur downfield at approx. $7 ppm$ $"7 ppm"$ . The ring current of the conjugated $π$ $pi$ electrons act to deshield exocyclic protons on the aromatic ring, hence the downfield absorption, far removed from aliphatic and vinyl absorptions.
