Isolation and purification of the organic compound from its natural source or synthesis Characterization through various analytical techniques such as spectroscopy, chromatography, and elemental analysis Structural elucidation to determine the arrangement of atoms in the compound Further study to understand the properties, reactions, and potential applications of the organic compound.
Each compound has a specific absorption spectra.
Infrared spectroscopy is capable of providing a complex fingerprint region which is unique to the compound being examined. This allows the compound to be identified by matching its sample spectrum to the standard. Computer control of instruments also allows this to be readily carried out.
FTIR spectroscopy cannot be used to detect all the vibration modes in a molecule. It can be used only to study the non-symmetrical vibrational state in an atom. Using Raman Spectroscopy one can study the symmetric stretch of the atom. For example the symmetric stretch of CO2 which cannot be studied by FTIR can be studied by Raman Spectroscopy. Here the permanent dipole moment of the molecule during a vibrational cycle does not change as it does not involve polarization. As a result, this mode cannot absorb infrared radiation. In many instances, vibrational modes that are not observed by infrared absorption can be studied by Raman spectroscopy as it is the result of inelastic collisions between photons and molecules
In UV spectroscopy, a red solution could indicate the presence of a compound that absorbs light more in the visible range rather than in the UV range. This could be due to the presence of colored impurities in the sample or the compound itself having strong absorbance in the visible region. Further analysis, such as UV-Vis spectroscopy, can provide more information on the specific properties of the red solution.

Spectroscopy
Infrared (IR) spectroscopy measures the vibrations of chemical bonds, providing information about functional groups in a compound. Ultraviolet (UV) spectroscopy measures the absorption of light in the UV range, giving insight into the electronic structure of a compound. Both techniques are valuable for identifying and analyzing chemical compounds, with IR being more useful for functional group identification and UV for electronic structure analysis.

Scientists can identify the composition of a compound through techniques such as mass spectrometry, nuclear magnetic resonance spectroscopy, and infrared spectroscopy. These methods help determine the elements present, their arrangement, and the functional groups within the compound. By comparing data from these analytical techniques with known compounds, scientists can identify the composition of an unknown compound.
UV-Vis spectroscopy measures the absorption of ultraviolet and visible light by a compound, providing information on electronic transitions. IR spectroscopy measures the absorption of infrared light by a compound, providing information on molecular vibrations. UV-Vis is useful for analyzing conjugated systems and determining the presence of certain functional groups, while IR is useful for identifying specific functional groups and determining molecular structure. Both techniques are valuable for characterizing chemical compounds and can be used together for a more comprehensive analysis.

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.
Infrared spectroscopy is used to identify functional groups in a chemical compound by measuring the absorption of infrared light by the compound. Different functional groups absorb infrared light at specific wavelengths, allowing scientists to identify the presence of specific functional groups in a compound based on the pattern of absorption peaks in the infrared spectrum.
