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 ...

Ultrafast extreme ultraviolet (XUV) spectroscopy is a powerful technique for probing the dynamics of atoms and molecules with attosecond time resolution. However, conventional XUV absorption ...

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 top panel illustrates halide substitution in cesium lead halide (CsPb(Br/Cl)₃) nanocrystals, where photoirradiation induces exchange between bromide and chloride ions, altering the Br/Cl ratio.

A team at the Institute for Basic Science (IBS) Center for Molecular Spectroscopy and Dynamics (CMSD) has developed a new spectroscopic technique to monitor changes in perovskite nanomaterials in real ...
