# The use of subindices with greek letters

I need to use subindices with greek letters. But I find that the result is sometimes decipherable.

Examples:

$\alpha_{H}$, $\gamma_{H}$


Do you have any suggestion in that regard? Of course, I do not want to use another subindex than "H".

try it this way:

\def\H{\rule{0pt}{1.5ex}H}

$\alpha_H \gamma_H$ $\alpha_{\H} \gamma_{\H}$

Or just an empty supercript $\alpha^{}_{H}$ often helps – Danie Els May 18 '11 at 7:24
@Herbert Could you please explain why that works? Thanks! – qed Feb 13 '13 at 15:16
@CravingSpirit: It insert an invisible vertical rule before H which is always of the same height. – Herbert Feb 14 '13 at 7:09
@Herbert Oh, I see. It also has something to do with the length of the rule, the longer it is, the lower the "H" will sink. Thanks! – qed Feb 15 '13 at 15:06
