What are the characteristics of absorption bands in UV spectroscopy and how do they contribute to the analysis of a sample?

Absorption bands in UV spectroscopy are characterized by their specific wavelengths at which a sample absorbs light. These bands are unique to different molecules and can provide information about the chemical structure and composition of a sample. By analyzing the intensity and position of absorption bands, scientists can identify and quantify substances present in a sample, aiding in its analysis and identification.
