Suppose, I have something like

\overline{q}_{l m_1}'(i) \overline{q}_{l m_2}'(i) \overline{q}_{l m_3}'(i)

Now, this renders to

LaTeX rendering of code above

which looks rather unpleasant. How can I reduce the spaces in front of the opening parentheses? The q's are functions of i, hence there should be no space at all.

I am using amsmath and mtpro2 for Times font in math mode, but the problem occurs regardless of these settings.

Many thanks in advance, Lennex

  • Welcome to TeX - LaTeX! Standard commands would be \! or \mkern-3mu or whatever number of mu (math units) you need. – Andrew Swann Dec 15 '15 at 13:33
  • I'd use \bar instead of \overline. – egreg Dec 15 '15 at 13:42

You may set small spaces (1/6 of a quad) manually: negative \! and positive \,:

\overline{q}_{l m_1}'\!(i)\,\overline{q}_{l m_2}'\!(i)\,\overline{q}_{l m_3}'\!(i)
