In Dirac Notation of quantum mechanics, the representation of a state. The complex conjugate of a ket. Denoted as <f| where f can be a wave function or a set of quantum numbers. Analogous to a row vector in linear algebra. The name originates from separating a bracket ( <f|f'> ) into a bra ( <f| ) and a ket ( |f'> ).
<nlm| is a bra representation of the Hydrogen atom with quantum numbers n, l, and m.
