Excited State of an Atom: Examples and Description

WebAn atom or molecule or ion and its electrons are said to be in the ground state when they are at the lowest possible energy level. If they are at a higher energy level, they are said to be excited. Electrons that have higher energy than the ground state are said to be excited. WebApr 4, 2024 · For phosphorescence, things are a bit different (see Fig. 4). There are again an S 0 ground state and the two excited states, S 1 and S 2. Additionally, there is an excited triplet T 1 state which lies energetically between the S 0 and S 1 state. The electrons again have antiparallel spins in the ground state. In quantum mechanics, a singlet state usually refers to a system in which all electrons are paired. The term 'singlet' originally meant a linked set of particles whose net angular momentum is zero, that is, whose overall spin quantum number . As a result, there is only one spectral line of a singlet state. In contrast, a doublet state contains one unpaired electron and shows splitting of spectral li… reformations spiel
