How does absorption spectroscopy work to analyze the interaction of light with matter?
Absorption spectroscopy works by measuring how much light is absorbed by a substance at different wavelengths. When light passes through a sample, certain wavelengths are absorbed by the molecules in the sample, causing them to move to higher energy levels. By analyzing the amount of light absorbed at each wavelength, scientists can determine the chemical composition and concentration of the sample.

What are the differences between IR spectroscopy and UV-Vis spectroscopy in terms of their applications and principles?
IR spectroscopy and UV-Vis spectroscopy are both analytical techniques used to study the interaction of light with matter. IR spectroscopy is primarily used to identify functional groups in organic molecules by measuring the vibrations of chemical bonds. It is sensitive to the presence of specific functional groups such as carbonyl, hydroxyl, and amino groups. UV-Vis spectroscopy, on the other hand, is used to determine the electronic transitions of molecules, providing information about the presence of conjugated systems and chromophores. It is commonly used to quantify the concentration of a compound in solution. In terms of principles, IR spectroscopy measures the absorption of infrared radiation by molecules, while UV-Vis spectroscopy measures the absorption of ultraviolet and visible light. The differences in the types of radiation used result in different applications and information obtained from each technique.
