Near-IR absorption spectrum of dichloromethane showing complicated overlapping overtones of mid IR absorption features. Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). [1]

2024年2月27日 · NIR spectroscopy analyzes how light and matter interact, generating a spectrum. Generally, light is described by wavelength rather than applied energy when spectroscopic methods are applied. NIR spectroscopy functions in the wavelength range of 780 to 2500 nm, which is the near-infrared region of the electromagnetic spectrum.

2023年1月23日 · Near-infrared light (NIR) is a type of infrared light that is the closest on the electromagnetic radiation spectrum to human sight. However, since it is further than what we can see, the wavelengths recorded from NIR are just slightly longer, from …

2023年1月3日 · Near-infrared (NIR) spectroscopy is a powerful analytical technique that has found wide applications in various fields, including chemistry, pharmaceuticals, agriculture, food science, and materials science. It involves the interaction of near-infrared light with matter to obtain valuable information about its molecular composition and structure.

2018年7月16日 · In the third article in our new series exploring Near-Infrared Spectroscopy (NIR), we explore the information that can be extracted from NIR spectra. NIR spectra are notoriously difficult to interpret mainly due to broad, overlapping and non-specific nature of …

2005年6月15日 · Near-infrared spectroscopy (NIRS) is a fast and nondestructive technique that provides multi-constituent analysis of virtually any matrix. It covers the wavelength range adjacent to the mid infrared and extends up to the visible region.

Near-Infrared Light (NIR) is the section of electromagnetic radiation (EMR) wavelengths nearest to the normal range but just past what we can see. Visible light is the smallest section of the electromagnetic (EM) radiation field .

2025年1月10日 · Near-infrared spectroscopy (NIRS) is a non-invasive monitoring technique that utilizes light transmission and absorption to continuously evaluate regional tissue oxygen saturation, delivery, and metabolism.

2014年1月1日 · In the electromagnetic spectrum, near infrared (NIR) region covers between 780 nm to 2500 nm. The developments of new NIR techniques like NIR imaging (NIR cameras, NIR hyperspectral imaging systems), Fourier Transform (FT)-NIR …

2018年1月1日 · As NIR spectroscopy utilizes light of low intensity, it will necessarily produce less sensitive responses in the excited molecules (Wetzel, 1998). To compensate for this lower sensitivity, the noise levels detected by the instrument have to be kept to a …
