Salt slurries in petri dishes with methanol are ignited and characteristic colors for various metals are observed. Colors of emission spectra are due to loosely-bound valence electrons being excited ...

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

These spectra can provide detailed information about hyperfine structures: tiny variations in atomic energy levels that ...

The authors demonstrate how this framework enables the prediction of 3D atomic arrangements from XANES spectra. "Our method bridges a crucial gap between spectroscopic analysis and precise ...
