Spectroscopy is a popular analytical technique for detecting functional groups in the molecule and it studies the interaction between electromagnetic radiation and matter.
The advantage of IR spectroscopy:
The advantage of IR spectroscopy:
1. Qualitative and quantitative analysis: One of the key advantages of Infrared spectroscopy is without destroying the sample it can provide qualitative and quantitative chemical information.
2. Sample Preparation: The major advantage of infrared spectroscopy is that the sample does not need any particular preparation. 3. Sensitive and Time-saving technique: IR spectroscopy is very sensitive, hence it required minimum sample quantity to scan the sample spectrum and it takes a few seconds to scan a whole range of IR.
4. It's versatility: Solid, liquid, gases and semisolid samples can be analyzed by the IR spectroscopy.
5. Easy for interpretation: The Peak intensities, peak positions, peak widths, shapes, and functional groups provide all helpful information.
The disadvantage of IR spectroscopy:
- Disadvantages include sometimes difficult handling procedures and maintenance of the sample cells.
- There are no infrared spectra in atoms or monatomic ions, hence it cannot analyses.
- To use infrared spectroscopy is that it requires very sensitive and properly tuned devices.
- The sample having aqueous solutions and complex mixtures are complicated to analyze by infrared spectroscopy.
