Analyzing Infrared Spectra
Infrared (IR) spectroscopy is a powerful analytical technique used to identify and characterize organic compounds. It relies on the principle that different functional groups within a molecule absorb specific frequencies of infrared radiation, resulting in a unique spectrum. When interpreting an IR spectrum, spectroscopists search for characteristic absorption peaks that correspond to various functional groups, such as alcohols, aldehydes, ketones, and carboxylic acids. These peaks provide valuable information about the structure and composition of the sample.
- For example, a strong absorption peak around 3300 cm-1 indicates the presence of an alcohol group (–OH).
- Additionally, a peak around 1700 cm-1 suggests the presence of a carbonyl group (C=O), which can be found in aldehydes, ketones, or carboxylic acids.
By carefully analyzing the position, intensity, and shape of absorption peaks, researchers can gain insights into the molecular structure and identify unknown compounds.
