Värähtelyspektroskopia

Värähtelyspektroskopia, also known as vibrational spectroscopy, is a scientific technique used to study the vibrational motions of atoms, molecules, or ions. This method involves the interaction of matter with electromagnetic radiation in the infrared or Raman regions of the spectrum. The principle behind this technique is that molecules absorb or emit radiation at specific frequencies when their atoms or groups of atoms undergo vibrational motions.

In vibrational spectroscopy, the absorption or emission of radiation is measured as a function of frequency or wavelength. The resulting spectrum provides information about the molecular structure, bonding, and dynamics. The technique is widely used in chemistry, physics, and materials science to identify and characterize compounds, study molecular interactions, and investigate the properties of materials.

There are several types of vibrational spectroscopy, including infrared spectroscopy, Raman spectroscopy, and infrared-ultraviolet double resonance spectroscopy. Each method has its own advantages and is suited to different types of samples and applications. Vibrational spectroscopy is a powerful tool for researchers due to its sensitivity, specificity, and non-destructive nature. It allows for the study of a wide range of samples, from gases and liquids to solids and even biological molecules.
