Spectroscopy remains a cornerstone of modern science, underpinning our ability to probe the intrinsic energy levels of atoms and molecules with remarkable precision. By interpreting the interaction of ...
The ion of the hydrogen molecule is ideally suited for making ultra-precise measurements of important physical constants. Physicists at Heinrich Heine University Düsseldorf (HHU) headed by Professor ...
A special type of laser spectroscopy has been used by researchers in Australia to measure the velocities of atoms in caesium vapour. The technique could allow researchers to infer both the temperature ...
