Infrared (IR) spectroscopy is a powerful analytical technique that has been widely used in various fields, including chemistry, biology, and physics. It is based on the absorption of infrared radiation by molecules, which leads to the excitation of their vibrational modes [1]. The resulting spectrum provides a unique fingerprint of the molecule, allowing for its identification and characterization. IR spectroscopy is an essential tool for the identification and characterization of organic molecules. Its advantages include its non-destructive nature, its ability to provide qualitative and quantitative information, and its versatility in different sample environments [2].
One of the major advantages of IR spectroscopy is its nondestructive nature. Unlike other analytical techniques such as mass spectrometry, IR spectroscopy does not require the ionization of the molecule, which can cause fragmentation or alteration of the sample. This makes IR spectroscopy an excellent choice for the analysis of delicate samples or samples that are difficult to prepare [3].
Another advantage of IR spectroscopy is its ability to provide qualitative and quantitative information. The spectrum obtained from an IR measurement provides a unique fingerprint of the molecule, allowing for its identification and characterization. Additionally, the intensity of the absorption peaks in the spectrum can be used to determine the concentration of the molecule in a sample, providing quantitative information [4].
IR spectroscopy is also versatile in different sample environments. It can be used to analyze samples in various states, including gases, liquids, and solids. Additionally, it can be used to analyze samples in different environments, such as vacuum, air, or inert gas. This versatility makes IR spectroscopy a valuable tool in many fields, including environmental science, pharmaceuticals, and materials science. Despite its advantages, there are some limitations to IR spectroscopy. One limitation is its inability to provide information about the stereochemistry of molecules. IR spectroscopy only provides information about the vibrations of functional groups, not their three-dimensional arrangement. As a result, other techniques, such as NMR spectroscopy, must be used to determine the stereochemistry of a molecule [5]. Another limitation of IR spectroscopy is its limited ability to detect some functional groups, such as metals or halogens. These groups do not exhibit strong IR absorption peaks, which can make their identification difficult using IR spectroscopy alone. In these cases, other analytical techniques, such as X-ray crystallography or atomic absorption spectroscopy, must be used to identify these functional groups.
In conclusion, while there are some limitations to IR spectroscopy, these can often be overcome by combining it with other analytical techniques. Overall, IR spectroscopy will continue to play a critical role in the analysis of organic molecules in the future.
One of the key advantages of IR spectroscopy is its ability to provide a non-destructive analysis of samples. Unlike some other analytical techniques, IR spectroscopy does not require any sample preparation that would alter or damage the sample. Additionally, IR spectroscopy is a relatively fast and inexpensive method compared to other analytical techniques such as Nuclear Magnetic Resonance (NMR) spectroscopy.
One of the limitations of IR spectroscopy is its sensitivity to water vapor, which can interfere with the analysis of some samples. This is because water vapor absorbs infrared radiation in the same spectral region as many of the functional groups found in organic molecules. To overcome this problem, special sample cells or desiccators are used to remove water vapor from the sample environment.
