# The Nature of Interaction Between Materials Afflicted by Spectroscopic Analysis

Studying the properties of a particular material is important in manufacturing. If not for the countless successful experiments on the properties of raw materials, the planet would have not developed into its current state. There may have been no accurate distinction between food and poison, corrosive and gentle substances, ferrous and non-ferrous metals, etc. Spectroscopy, the analysis of the interaction between matter and radiated energy, has played an important role in this leap. This article discusses how spectroscopy works in terms of the interaction of the electromagnetic radiation between a source and a material being studied.

Basically, spectroscopy involves the excitation of matter through electromagnetic radiation or light. Although visible light is part of its scope, it intends to create helpful information by utilizing invisible light instead. Invisible light refers to the electromagnetic radiations over the electromagnetic spectrum that are beyond the spectral region. They're known for their short wavelengths but low frequency, which impedes the human eye to visualize them. The most used and most extensively useful for industrial purposes will be the infrared (IR) and near infrared (NIR).

IR and NIR have already been used in spectroscopy for a lot of years. Unlike other kinds of invisible light, they cause the smallest amount of injury to a substance subject to [types of cuvettes](https://cotslab.com/guide-uv-vis-spectrophotometer-and-fluorescence-cuvettes/) analysis and therefore perfect for that purpose. In the application form, IR or NIR is dispersed or introduced to a material. The devices used include spectrographs, spectrophotometer, spectral analyzers, and spectrometers. The power in the material, induced by the excitement occurring between atoms or molecules, provides the required information about the material's properties.

The nature of interaction between the radiated energy and the material being studied can vary greatly depending on the properties of the material. Absorption, one of the very most common forms of interaction, occurs when the radiated energy passes through the material involuntarily. A near infrared spectrophotometer can be used to assess the spectral bandwidth and linear array of absorption. These changes in the frequency through the interaction will tell the properties of the substance.

In some instances, the material emits radiated energy through the induction of the foundation, as an example, flame or spark. This explains the fluorescent effect on some molecules when induced with a beam of light such as for instance ultraviolet (UV). In near infrared spectroscopy, the emitted energy as an application of interaction with the foundation provides vital information about the material's properties.

Another interaction that could indicate the property of a particular substance is elastic scattering and reflection. The near infrared reflectance or elastic scattering effect on a substance allows an investigator to examine the arrangement of atoms or molecules in a particular compound, thereby eliminating the requirement for actual viewing through an electron microscope.
