Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

What is Atomic Absorption Spectrometry? AAS is a technique for determining how much of a specific element is present in the specimen under study. The uptake of optical radiation by neutral atoms in ...

Electromagnetically induced absorption (EIA) is a subtle quantum optical phenomenon wherein the application of coherent light fields to an atomic vapour engenders an unexpected increase in absorption ...

XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an ...
