Symbols
\newcommand{\nucl}[3]{%
\ensuremath{%
\phantom{\ensuremath{^{#1}_{#2}}}%
\llap{\ensuremath{^{#1}}}%
\llap{\ensuremath{_{\rule{0pt}{.75em}#2}}}%
\mbox{#3}%
}%
}
and in the text you can use it in mathmode, too $\nucl{235}{92}{U}$![](/misc/symbol0.gif")
Package chemtex
Write in latex preamble
\usepackage{chemtex}
and in text in tex (red) for example
\initial
\parbox{.3\textwidth}{\hetisix{Q}{Q}{Q}{Q}{Q}{Q}{O}{Q}{O}\xi=-85\fuseup{Q}{Q}{Q}{Q}{D}{Q}{D}{Q}{D}}
put all in one line! The output is a chemical structure
The whole package maybe part of your local tex-installation. Otherwise it's available at CTAN.
Package xymtex
This package needs some more packages, especially epic.sty. For the following example write in preamble
\usepackage{epic,carom,hetarom}
and in text in tex (red)
\decaheterov[aegi]{4==0}{3D==0}
Which gives the chemical structure:![](/misc/xymtex.gif")
The whole package maybe part of your local tex-installation. Otherwise it's available at CTAN.
Package ochem
ochem is a very powerful package and has a lot of options.
\usepackage{ochem}
and in text in tex (red)
\begin{chemistry}
formula(L,R,"A chemical structure",HR,20)
{ ring(){ 5: ring(,1,H){3: atom("O");4:
bond(30,=C) atom("O");}
;}
}
\end{chemistry}
The package produces the file <name>.chm. on this ochem needs a run with the perl program chemie.pl, which is
part of the package.
