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 ...

Plasmon-enhanced molecular spectroscopies have attracted tremendous attention as powerful detection tools with ultrahigh sensitivity down to the single-molecule level. The optical response of ...

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

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 frozen dwarf planet at the edge of sunlight.

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

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 ...
