What is basic difference between UV visible and IR spectroscopy?

Question

Accepted Answer

UV-Vis spectroscopy measures absorption of light in the visible and ultraviolet range, while IR spectroscopy measures absorption of light in the infrared range.

UV-Vis spectroscopy is used to determine the concentration of a sample, while IR spectroscopy is used to identify functional groups in a molecule.
UV-Vis spectroscopy uses a UV-Vis spectrophotometer, while IR spectroscopy uses an IR spectrophotometer.
UV-Vis spectroscopy is commonly used in the analysis of organic compounds, while IR spectroscopy is used in the analysis of both organic and inorganic compounds.
UV-Vis spectroscopy is sensitive to conjugated systems, while IR spectroscopy is sensitive to the presence of polar functional groups.
Examples of UV-Vis spectroscopy applications include determining the concentration of DNA or protein in a sample, while examples of IR spectroscopy applications include identifying the presence of carbonyl groups in a molecule.
