X-ray absorption spectroscopy (XAS) is a popular characterization technique for probing the local atomic structure and electronic properties of materials and molecules. Because atoms of each element ...

Spectroscopy has many applications, ranging from fundamental tests of quantum electrodynamics and investigations of molecular structure to environmental sensing, biomedical diagnostics and industrial ...

The James Webb Space Telescope has detected anunexplained infrared absorption signal, appearing as a distinct spectral ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

While studying Pluto and Saturn’s largest moon Titan, researchers spotted a missing band of light in their spectral ...

Titan and Pluto sit at opposite ends of the solar system, one a giant moon wrapped in thick orange haze. The other is a ...

Researchers at Uppsala University have calculated that the sun contains 55% more silver than previously estimated. The ...

The sample preparation before conducting an infrared spectroscopy (IR) study is as critical as the study itself, and the samples which are difficult to dissolve in any IR-transparent solvent are mixed ...

Digital imaging that includes spectral estimation can overcome limitations of typical digital photography, such as limited color accuracy and constraints to a predefined viewing condition or a ...
