如何能将该方案与红线垂直对齐?
\documentclass{article}
\usepackage[margin=1.5cm,top=1cm,headheight=16pt,headsep=0.1in,heightrounded]{geometry}
\usepackage{chemfig}
\setchemfig{%
% %scheme debug=true,
arrow offset=9pt,
arrow coeff=0.7,
% compound sep=5em,
+ sep left=0.6em,
+ sep right=0.6em,
atom sep=1.25em,
fixed length=true
}
\begin{document}
\begin{tikzpicture}
\draw[red](0,-.59) --++ (12,0);
\schemestart
\rotatebox{-90}{\chemfig{**6(---(-)-(-)--)}}
\arrow{<=>}
\rotatebox{-90}{\chemfig{**6(--(-)--(-)--)}}
\arrow{<=>}
\rotatebox{-90}{\chemfig{**6(-(-)---(-)--)}}
\schemestop
\end{tikzpicture}
\end{document}

您只能使用 chemfig。不可见的键可调整分子位置。
