# Is it possible to typeset left and right angle brackets?

I would like to typeset the following in a Mathematica notebook:

$$\langle P \rangle$$

Is it possible to typeset left and right angle brackets? In $\LaTeX$, they are given by \langle and \rangle. I do not see such symbols in the documentation, but I may be overlooking them.

It's in the Writing Assistant - Typesetting palette. You can also use AngleBracket[...], or type esc < esc. –  freddieknets Sep 12 '12 at 16:14

 \[LeftAngleBracket]P\[RightAngleBracket]

Mathematica provides angle-bracket symbols \[LeftAngleBracket] and \[RightAngleBracket], which act like other brackets.

You can easily input them using "Esc < Esc" and "Esc > Esc".

Mathematica will also parse $\langle a, b, c, ...,z\rangle$ as AngleBracket[a, b, ..., z], which is useful if you're generating a typeset expression.

For the particular usage of angle brackets in quantum mechanics, there are also the convenient input aliases "Esc bra Esc", "Esc ket Esc", and "Esc braket Esc" for , , and respectively.

In the form of an operator:

AngleBracket[P]


outputs as $\langle P \rangle$, which, under the hood, is just:

\[LeftAngleBracket]P\[RightAngleBracket]
