Absorption spectroscopy is a fundamental analytical technique widely used in various scientific disciplines, including chemistry, biology, and material science. It effectively analyzes substance ...

IR spectroscopy, or infrared spectroscopy, is an analytical technique used to identify and study chemical substances based on their interaction with infrared radiation. It measures the absorption of ...

It provides critical insights into the molecular structure and composition of materials by measuring their infrared absorption spectra. This article delves into the definition, principle of operation, ...

Atomic Force Microscopy (AFM) and Infrared (IR) Spectroscopy are powerful analytical techniques used to study materials at the nanoscale. AFM provides high-resolution topographical images of ...

Researchers from Tokyo Metropolitan University have developed a new dye that can strongly absorb second near-IR radiation and ...

The team’s new compound can absorb electromagnetic waves in the NIR-II part of the spectrum, where waves can penetrate deeper into human tissue and generate heat, leading to photoacoustic emissions.

On the other hand, infrared spectroscopy is a powerful optical technique for precise chemical identification, as each material has unique absorption bands in the "fingerprint" region due to its ...

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...

QCL-IR spectroscopy is based on the well-acknowledged Beer-Lambert absorption concept. It is, therefore, a technique for not just spectrally fingerprinting unknown chemicals but also directly ...

The Spectrum Two instrument is best suited for day-to-day analysis, enabling users to confidently carry out quick, accurate IR analysis and ensure the quality of their materials over an extensive ...
