Explore the Basics of Vibrational Spectroscopy: Applications in Science and Industry

Introduction:
Vibrational spectroscopy is a technique used in analytical chemistry that provides information on the molecular vibrations of a sample. It is widely used in various fields, including materials science, biochemistry, and pharmaceuticals. In this essay, we will explore the basics of vibrational spectroscopy, its different types, and its applications in various fields.

Basics of Vibrational Spectroscopy:
Vibrational spectroscopy involves the interaction of light with the molecules of a sample, where the energy from the light is absorbed by the molecules, causing them to vibrate. These vibrations can be observed and analyzed to provide information on the molecular structure of the sample. There are two main types of vibrational spectroscopy: infrared (IR) spectroscopy and Raman spectroscopy.

Infrared Spectroscopy:
Infrared spectroscopy is a widely used technique in analytical chemistry that measures the absorption of infrared radiation by a sample. The infrared radiation is directed through a sample, and the amount of radiation absorbed by the sample is measured. The results are then analyzed to identify the molecular vibrations of the sample.

Infrared spectroscopy is used to identify the functional groups in a molecule. Different functional groups absorb different wavelengths of infrared radiation, allowing them to be identified. For example, the carbonyl group in a molecule absorbs a specific wavelength of infrared radiation, which can be used to identify the presence of the carbonyl group in the molecule.
