Photoelectron spectroscopy (PES) has emerged as a cornerstone technique for probing the electronic structure of organic molecules, offering direct measurement of binding energies and orbital character ...

Photoelectron spectroscopy of molecular dynamics exploits the interaction of electrons and photons to resolve the electronic structure and accompanying nuclear motion of molecules on ultrafast ...

X-ray photoelectron spectroscopy is based on the same principle as all photoelectron spectroscopy methods. If a molecule or material is irradiated with light of a known energy above the ionization ...

Photoelectron spectroscopy (PES) is a surface-sensitive analytical technique that provides information about the elemental composition, chemical state, and electronic structure of a material's surface ...

The basic physical process of irradiating a material with photons of a known energy and measuring the ejected photoelectrons has remained unchanged over six decades since it was first commercialized.

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light pulses. This is thanks to a new measurement technique ...

As a key precursor in the formation of new particles, sulfuric acid (H 2 SO 4) plays an important role in the formation of aerosols and clouds in the atmosphere. Gas-phase sulfuric acid molecules can ...

Photoelectron techniques comprise experimental methods that detect and analyze electrons emitted from atoms, molecules, solids, or surfaces upon irradiation with photons, typically in the ultraviolet ...

An X-ray photoelectron spectrometer is an impressive bit of kit. The relatively low energy of the detected photoelectrons dictates that the experiments are performed in ultra-high vacuum. The ...

New research shows that X-ray photoelectron spectroscopy (XPS) can give misleading analysis results due to an erroneous assumption during calibration. X-ray photoelectron spectroscopy (XPS) is often ...
