Infrared Spectroscopy: Principles and Techniques
Infrared (IR) spectroscopy is a valuable analytical technique used to identify and quantify chemical compounds. It relies on the principle that molecules absorb infrared radiation at specific wavelengths corresponding to their vibrational modes. When an IR beam passes through a sample, certain wavelengths are absorbed by the molecule's bonds, causing them to vibrate. The resulting absorption spectrum provides a unique fingerprint of the molecule, allowing for its identification and structural elucidation.
There are several types of IR spectroscopy, including transmission, attenuated total reflection (ATR), and Fourier transform infrared (FTIR) spectroscopy. Each technique provides distinct advantages depending on the nature of the sample and the information required. Transmission spectroscopy employs a beam of IR radiation passing through a sample in a transparent medium, while ATR spectroscopy measures the absorption of IR radiation reflected from the sample surface. FTIR read more spectroscopy uses an interferometer to measure the interference pattern caused by the interaction of IR radiation with the sample, providing high sensitivity and resolution.
Uses of IR spectroscopy are extensive in various fields, including organic chemistry, biochemistry, pharmaceuticals, materials science, and environmental analysis. It is an essential tool for identifying unknown compounds, determining molecular structures, quantifying components in mixtures, and monitoring chemical reactions.
