Hello:
I am trying to place electron dots around an atom. The atom will then be used
in xymtex to draw a large molecule.
Can some one help me to place the electrons around an atom in an unequivocal
way?
For the code below, numbers 1 and 2 are OK because the left side and right side
electrons are put around the atom separately.
But number 3 is bad because the left and right electrons are placed at the same
time, and the origin is shifted.
Numbers 4, 5, and 6 are really bad.
Is there a way to do this so the electrons are placed in an invariant manner?
The simple code is:
\documentclass[a4paper]{article}
\usepackage{pstcol}
\usepackage{pst-node}
\usepackage{pst-slpe} % CTAN:graphics/pstricks/contrib/pst-slpe
\def\TwoDotsr{\psdots[dotsize=1pt, linecolor=black](0.05,0.15)(0.05,0.30)}
\def\TwoDotsl{\psdots[dotsize=1pt, linecolor=black](-0.05,0.15)(-0.05,0.30)}
\def\TwoDotsb{\psdots[dotsize=1pt, linecolor=black](-0.40,-0.05)(-0.300,-0.05)}
\def\TwoDotst{\psdots[dotsize=1pt, linecolor=black](-0.40,0.50)(-0.300,0.50)}
\begin{document}
{\LARGE
\begin{enumerate}
\item O\TwoDotsr
\item \TwoDotsl O
\item O\TwoDotsl\TwoDotsr
\item O \TwoDotsb
\item O \TwoDotst
\item \TwoDotsb\TwoDotsl O \TwoDotsr\TwoDotst
\end{enumerate}
}
\end{document}
I really would appreciate your suggestions.
Kind regards,
Angelo
