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 ...

The review discusses innovations in quartz-enhanced laser spectroscopy, emphasizing QEPAS and LITES for improved sensitivity in trace gas sensing technologies.

What is X-ray Absorption Spectroscopy (XAS)? X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique that probes the local atomic and electronic structure of materials by measuring the ...

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 ...

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could. Now, ...

Can you briefly explain what transient absorption (TA) spectroscopy is and why it is important? Transient absorption (TA) spectroscopy is a pump-and-probe technique used to study the absorption of ...

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) ...

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 ...

Photothermal AFM-IR, commonly referred to as AFM-IR, is an analytical technique used to understand the chemistry of a material at the nanoscale. It combines the nanoscale spatial resolution of atomic ...
