UV spectroscopy and IR spectroscopy are both analytical techniques used to study the interaction of light with molecules. UV spectroscopy measures the absorption of ultraviolet light by molecules, providing information about electronic transitions and the presence of certain functional groups. On the other hand, IR spectroscopy measures the absorption of infrared light by molecules, providing information about the vibrational modes of the molecules and the presence of specific chemical bonds. In terms of applications, UV spectroscopy is commonly used in the study of organic compounds and in the pharmaceutical industry, while IR spectroscopy is widely used in the identification of unknown compounds and in the analysis of complex mixtures.
UV spectroscopy involves the absorption of ultraviolet light by chemical compounds, while IR spectroscopy involves the absorption of infrared light. UV spectroscopy is used to analyze compounds with conjugated double bonds, while IR spectroscopy is used to identify functional groups in compounds. Both techniques provide valuable information about the structure and composition of chemical compounds, helping chemists identify and characterize unknown substances.
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.
UV-Vis spectroscopy is used to analyze the absorption of ultraviolet and visible light by molecules, providing information on electronic transitions. It is commonly used for analyzing organic compounds and determining their concentration. In contrast, IR spectroscopy measures the absorption of infrared light, providing information on molecular vibrations. This technique is useful for identifying functional groups in organic compounds and determining molecular structure. Overall, UV-Vis spectroscopy is more sensitive to electronic transitions, while IR spectroscopy is more sensitive to molecular vibrations.
Water has strong absorption bands in the IR region, which can interfere with the absorption bands of the sample being analyzed. This background noise can make it difficult to accurately interpret the IR spectrum of the sample. Additionally, water tends to have a broad and featureless absorption band in the typical IR region, making it a poor solvent for IR spectroscopy.

The force constant is a measure of the strength of a chemical bond. In IR spectroscopy, it affects the vibrational frequency of a molecule, which determines the position of peaks in the IR spectrum. Higher force constants result in higher vibrational frequencies and shifts IR peaks to higher wavenumbers.

IR spectroscopy works by using infrared beams to work out the structure of a chemical. The chemical is placed in an inert substance, e.g. Potassium Bromide. The refraction of the beams brings up a characteristic trace of the mystery compound, which can then be used to work out the structure.
Sodium chloride was used as crystal in infrared spectroscopy; but his hygroscopicity is a major disadvantage.
