IR spectroscopy is widely used in both research and industry as a simple and reliable technique for measurement, quality control and dynamic measurement. The instruments are now small, and can be transported, even for use in field trials. With increasing technology in computer filtering and manipulation of the results, samples in solution can now be measured accurately. Some machines will also automatically tell you what substance is being measured from a store of thousands of reference spectra held in storage . Other possible application of IR spectroscopy are listed below.
- IR spectroscopy has been highly successful for applications in both organic and inorganic chemistry. By measuring at a specific frequency over time, changes in the character or quantity of a particular bond can be measured. This is especially useful in measuring the degree of polymerization in polymer manufacture .
- IR spectroscopy is useful for identifying substances and confirming their identity. Therefore it also has a forensic purpose: with the use of IR spectroscopy alcohol, drugs, fibers and paint could be analyzed .
- IR spectroscopy has also been successfully utilized in the field of semiconductor microelectronics: for example, this technique can be applied to semiconductors like silicon, gallium arsenide, gallium nitride , zinc selenide, amorphous silicon, and silicon nitride .
- Techniques have been developed to assess the quality of tea-leaves using IR spectroscopy .
