Quizplus · Accepted Answer

The UV spectrum is useful for determining conjugation resulting in electronic transitions. This is because conjugation causes a shift in the energy levels of the molecule, resulting in the absorption of UV light. Therefore, by analyzing the UV spectrum, we can determine the degree of conjugation in the molecule.
