Rydberg atoms are excited atoms that contain one or more electrons with a high principal quantum number. Due to their large size, long-range dipole-dipole interactions and strong coupling to external fields, these atoms have ...
In synthetic organic chemistry, so-called cycloadditions are a particularly important class of reactions. With this type of reaction, ring-shaped molecules can be constructed simply and efficiently by joining ("adding") two ...
