NIR SPECTROSCOPIES Meaning and
Definition
-
NIR spectroscopies, or near-infrared spectroscopies, refer to a range of analytical techniques that utilize the near-infrared region of the electromagnetic spectrum for analyzing the molecular composition of substances. Near-infrared radiation typically falls within the wavelength range of 780 to 2500 nanometers.
These spectroscopic methods involve the measurement of the absorption, reflection, or transmission of near-infrared light by a sample. By examining the unique spectral characteristics exhibited by different materials, NIR spectroscopies can be employed for a wide range of applications in various industries.
NIR spectroscopies are particularly valuable in chemical analysis and quality control processes across sectors such as pharmaceuticals, food and agriculture, and environmental monitoring. They offer several advantages over other analytical techniques, including non-destructiveness, rapid analysis, and the ability to evaluate samples in their natural state without the need for extensive sample preparation.
Sophisticated instruments, such as near-infrared spectrometers, are employed for NIR spectroscopic analysis. These instruments emit near-infrared light onto the sample and measure the changes in its absorption, reflection, or transmission properties, which are then used to determine the chemical composition, identify substances, or quantify specific constituents.
In summary, NIR spectroscopies utilize the near-infrared region of the electromagnetic spectrum to analyze substances based on their unique spectral characteristics. They are powerful tools for chemical analysis and quality control in various industries, offering non-destructive and rapid analysis capabilities with minimal sample preparation requirements.

Etymology of NIR SPECTROSCOPIES
The acronym NIR stands for "Near-Infrared", referring to a region of the electromagnetic spectrum beyond the visible light spectrum but still relatively close to it. NIR spectroscopy refers to the scientific technique of analyzing the interaction between near-infrared light and matter. The term spectroscopy comes from the combination of the Greek words "spectron", meaning "to look" or "to observe", and "skopein", meaning "to see" or "to examine". Therefore, NIR spectroscopy involves examining or observing matter using near-infrared light.
