D) UV-Vis spectroscopy
E) Raman spectroscopy

Question

Quizplus · Accepted Answer

UV-Vis spectroscopy is most useful for studying conjugation in organic compounds because it directly measures the absorption of light in the ultraviolet and visible regions, which is influenced by the extent of conjugation in a molecule. Conjugated systems have delocalized electrons that can absorb energy in the form of light, leading to electronic transitions that are observable with UV-Vis spectroscopy.
