<DT><A NAME="foot854">... charge</A><A
HREF="node7.html#tex2html7"><SUP>5.6</SUP></A></DT>
<DD>The charge directive, in conjunction with
the charges of atomic nuclei (which can be changed via the geometry
input, cf. Section <A HREF="node8.html#sec:cart">6.3</A>), determines the total number of
electrons in the chemical system. Therefore, a <TT>charge n</TT>
specification removes "n" electrons from the chemical system.
Similarly, <TT>charge -n</TT> adds "n" electrons.
