Infrared radiation represents electromagnetic {waves with wavelengths longer than visible light. It is emitted by all objects with temperature above absolute zero, and its intensity depends on the object's heat. While we cannot directly see infrared radiation, {it plays a crucial role in various
Fundamentals of Infrared Spectroscopy
Infrared (IR) spectroscopy is an analytical technique used to identify and quantify the rotational modes of molecules. It exploits the emission of infrared radiation with matter, providing a unique fingerprint of molecular structure. IR spectra are obtained by passing an beam through a sa
