Baird's rule, also known as Baird's law, is a principle in organic chemistry that pertains to the behavior of certain aromatic compounds during their electronic transitions. Specifically, it states that: **In a particular class of compounds, the singlet excited state is more stable than the triplet excited state.** This rule helps in predicting the reactivity and properties of certain polycyclic aromatic hydrocarbons.
