Attosecond transient absorption spectroscopy (ATAS) is an advanced technique that enables the direct observation of electron dynamics on the attosecond (10⁻¹⁸ second) timescale. By utilising isolated ...

Hidden features uncovered in X-ray signals are set to overturn a key scientific theory and fundamentally change how X-rays ...

Absorption spectroscopy is an analytical chemistry tool that can determine if a particular substance is present in a sample by measuring the intensity of the light absorbed as a function of wavelength ...

What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

The molecular gas outflow from the quasar includes hydroxyl (OH) (top). Due to the motion of the molecular gas toward the observer, the OH peak in the absorption spectrum (bottom, dashed blue line) ...
