Anion dynamics and photoelectron spectroscopy collectively offer a powerful means to elucidate the transient behaviour of negatively charged species in chemical reactions. This field explores how ...

RECENTLY vacuum ultraviolet photoelectron spectroscopy, using helium 21.2 eV radiation, has become of great value in examining ionization of compounds in the gas phase 1. If the technique could be ...

As the acronym suggests XPS (X-ray photoelectron spectroscopy) is a spectroscopic technique. An XPS spectrum is displayed as the number of photoelectrons collected by the detector as a function of ...

For the first time, and contrary to popular belief, scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it’s impossible to ...

Spectroscopy analyzes light to identify a celestial object's composition. Each element absorbs light at unique wavelengths, creating a spectral "fingerprint". The amount of light absorbed indicates ...
