Best insight from top research papers

Infrared frequency electromagnetic radiation refers to the range of electromagnetic radiation with frequencies between 20 and 14,500 cm^-1. This range falls within the infrared region of the electromagnetic spectrum. Infrared radiation is absorbed by chemical compounds that undergo a change in dipole moment during molecular vibrations, rotations, or combinations of both. The absorption of infrared photons excites molecular vibrations and phonons, providing information about the composition, structure, and thermal properties of materials. Infrared spectroscopy is a valuable analytical technique for qualitative and quantitative analysis in various fields, including food applications. It allows for rapid and simultaneous measurement of multiple constituents in a sample without the need for sample manipulation. Infrared heating systems utilize the transfer of radiant energy to heat objects and can result in fuel cost savings and improved temperature distribution.
