What is infrared spectroscopy forensics?

What does infrared spectroscopy detect?

It is used by chemists to determine functional groups in molecules. IR Spectroscopy measures the vibrations of atoms, and based on this it is possible to determine the functional groups. 5 Generally, stronger bonds and light atoms will vibrate at a high stretching frequency (wavenumber).

What is infrared spectrometry used for?

IR spectroscopic analysis is used to determine the various chemical functional groups present in the sample. Different functional groups absorb characteristic frequencies of IR radiation. IR spectroscopy is simply absorption measurement of different IR frequencies of a sample positioned in the path of an IR beam [79].

How does spectroscopy work in forensics?

Spectrophotometry is a process commonly used in the field of forensic science to trace evidence. This process uses infrared radiation and more commonly visible lights to ascertain light transmission, absorption, and reflective properties of any form of tiny materials.

Why is infrared spectroscopy important?

Infrared spectroscopy is an important technique in chemistry since it is an easy way to identify the presence of certain functional groups in a molecule.

How is infrared spectroscopy useful in identification of compounds?

Infrared spectroscopy in organic chemistry is most often used to identify chemical structures from the characteristic adsorption of IR light by different organic functional groups. Thus, the existence of hydroxyl groups, double bonds, and other active parts of a molecule can be deduced.

What is the principle of IR spectroscopy and its application?

The IR spectroscopy theory utilizes the concept that molecules tend to absorb specific frequencies of light that are characteristic of the corresponding structure of the molecules. The energies are reliant on the shape of the molecular surfaces, the associated vibronic coupling, and the mass corresponding to the atoms.
