Angle Bracket Right in LaTeX (\rangle)

Where it is used

Closing angle bracket that ends inner products, kets, averages and other angle-bracket notations.

\rangle closes what \langle opens: \langle f, g \rangle in Hilbert spaces, the Dirac ket |\psi\rangle, and presentations like \langle a, b \mid a^2 = b^3 \rangle. The greater-than sign > is not a substitute, since it is a relation with extra space around it and a flatter angle. When the contents are tall, as with fractions or sums, use \left\langle ... \right\rangle so both sides grow together. A ket used alone is written |\psi\rangle, which needs no matching \langle.

Minimal compilable example

Paste this into an empty .tex file and compile it with pdfLaTeX, XeLaTeX or LuaLaTeX.

\documentclass{article}
\begin{document}
Angle Bracket Right: $\rangle$

\[ |\psi\rangle = \alpha|0\rangle + \beta|1\rangle \]
\end{document}

Frequently asked questions

How do I write Angle Bracket Right in LaTeX?

Type \rangle in math mode, for example $|\psi\rangle = \alpha|0\rangle + \beta|1\rangle$. It works in plain LaTeX without loading any package.

Which package do I need for \rangle?

None. \rangle is part of standard LaTeX, so it compiles with nothing in the preamble but the document class.

Can I use \rangle in text mode, or only in math mode?

Only in math mode. Outside $...$ LaTeX stops with "Missing $ inserted", so write $\rangle$ in running text. If you only need the glyph in text, paste the Unicode character ⟩ instead (with XeLaTeX or LuaLaTeX and a font that has it).
