Root Explanation

Excimer is formed from "ex-" (meaning out of or from) and "cimer" (derived from the Greek word "chimos" meaning a chemical compound). The term refers to a type of molecule that exists only in an excited state, thus 'coming out' of a stable state to form a new compound.

Memory Tip

Think of 'ex-' meaning 'out of' and 'cimer' relating to a chemical compound, which helps you remember that an excimer is a molecule that comes out of a stable state.
