UV-Vis Spectroscopy and Conjugated Systems

A lesson that examines the effects of conjugation in relation to UV-Vis spectroscopy. We examine conjugation and p-orbital overlap and how this leads to lower HOMO to LUMO energy jumps, making wavelength increase.

How would you analyze aromatic systems using UV Spectroscopy?

[@ChemComplete]

UV uses a different process than polarity. UV uses electron excitation of pi electron systems. Different conjugated pi systems absorb different wavelengths. This means you scan the sample with a broad range of wavelengths and measure where you see an excitation response.
