![Chemfig/Chemnum 路线](https://linux22.com/image/354036/Chemfig%2FChemnum%20%E8%B7%AF%E7%BA%BF.png)
我正在写化学论文,其中涉及很多反应方案我如何添加显示的标签?我想将第一个化合物标记为 1,并且我希望这是一个 Latex 标签,这样我就可以在文本中引用它,然后在需要时更改标签。
以下是 MWE:
\documentclass{report}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\geometry{letterpaper, margin = 1in}
\DeclareFloatingEnvironment[fileext = los, listname = {List of Schemes}, name = Scheme]{scheme}
\begin{document}
\begin{scheme}[h!]
\centering
\includegraphics[scale = 0.7]{Carbdiazosyn}
\caption{Generation ...}
\label{carbdiazosyn}
\end{scheme}
\end{document}
答案1
Chemfig/Chemnum 路线
可能不是最明智的选择chemfig
,但只是表明这是可能的。您可能希望使用该包chemnum
来标记分子。它提供(除其他外)以下命令:
\cmpd{<main label>.<sublabel>} % <main label> produces the 1, <sublabel> produces the a, b etc.
\refcmpd{<main label>.<sublabel>} % Acts like \ref in normal circumstances
代码如下:
\documentclass[]{report}
\usepackage{chemfig,chemnum}
\usepackage[version=4]{mhchem}
\usepackage{geometry}
\geometry{letterpaper, margin = 1in}
\usepackage{newfloat}
\DeclareFloatingEnvironment[fileext = los, listname = {List of Schemes}, name = Scheme]{scheme}
\begin{document}
\begin{scheme}[ht]
\centering
%\schemedebug{true}
\schemestart[0,1.3]
\chemname{%
\chemfig{[:120]*3(-[@{a1}]N=[@{db}]N-[@{a2}])%
(-[:50,,,,red]\textcolor{red}{\ce{R1}})%
(-[@{r2}:-50,,,,red]\textcolor{red}{\ce{R2}})%
}
}{\cmpd{scheme.1}}
\arrow(.mid east--.mid west){->[$h\nu/\Delta$][$-$\ce{N2}]}
\chemname{%
\setlewis{0.8ex}{}{red}%
\chemfig[shift={(0,0.4)}]{[:-30]\textcolor{red}{\ce{R1}}%
-[,,,,red](\lewis{6:,})%
-[::60,,,,red]\textcolor{red}{\ce{R2}}}%
}{\cmpd[pre-label-code{scheme.2}}
\schemestop
\chemmove{%
\draw[shorten <=2pt, shorten >=3pt]%
(a1)..controls +(250:3mm) and +(340:3mm)..(db);
\draw[shorten <=2pt, shorten >=2pt]%
(a2)..controls +(320:3mm) and +(210:2mm)..(r2);
}
\caption[]{My scheme}\label{scheme1}
\end{scheme}
The arrows in \refcmpd{scheme.1} refer to electron movement! The compound in \refcmpd{scheme.2} is in red! Both \refcmpd{scheme.1, scheme.2} are in scheme \ref{scheme1}.
\end{document}
注意事项:我使用命令chemnum
中的命令\chemname
插入“标签”。我还使用mhchem
包在内排版化合物名称chemfig
。其余的只是chemfig
代码:-)
。
Auto-pst-pdf/Chemnum 路线(可能推荐)
该包还记录了替换第 9 节第 18 页图形chemnum
标签的方法.eps
文档根据手册,此工作流程如下(逐字引用):
- 创建方案并将临时标签(如)放置
TMP1
在TMP2
您想要复合标签所在的位置。- 将方案导出为
eps
或ps
图形,确保标签嵌入为文本字符串。- 包括
eps
。在每个临时标签\includegraphics
之前使用一次。\replacecmpd
我个人还没有尝试过(因为我不使用chemdraw
),所以我只会让你参考文档。(也许需要另一个正确记录此方法的答案)。无论如何,正如文档所建议的那样,如果您想继续使用,我认为这是可行的方法chemdraw
。
以下是文档中的示例代码:
% code for figure 2
\documentclass{standalone}
\usepackage{graphicx,auto-pst-pdf,chemnum}
\begin{document}
\replacecmpd{Alc}% replaces TMP1
\replacecmpd{EtherBr}% replaces TMP2
\includegraphics{scheme-tmp.ps} % Contains TMP1 and TMP2 as embedded text strings
\end{document}
答案2
我必须调整宽度以使子标题适合。
\documentclass{report}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\geometry{letterpaper, margin = 1in}
\usepackage{newfloat}
\DeclareFloatingEnvironment[fileext = los, listname = {List of Schemes}, name = Scheme]{scheme}
\usepackage{graphicx}
\usepackage{subcaption}
\DeclareCaptionSubType{scheme}
\captionsetup[subscheme]{font+=footnotesize}
\begin{document}
\begin{scheme}[htp]% h! is interpreted as "I am an idiot so replace this with something reasonable"
\centering
\sbox0{\includegraphics[scale = 0.7]{images/Carbdiazosyn}}% measure width
\usebox0\par
\makebox[1.1\wd0]{\parbox{0.45\wd0}{\subcaption{Compound 1}\label{compound1}}\hfill
\parbox{0.45\wd0}{\subcaption{Compound 2}\label{compound2}}}
\caption{Generation ...}
\label{carbdiazosyn}
\end{scheme}
\centering Of course, the reference will only return \ref{compound1}.
\end{document}
由于字幕是设计为适合给定的空间,并且在这种情况下我们希望它们适合一行,因此更容易不是使用 subcaption 包。
有多种格式选项可供选择。在本例中,我将标题放在左侧,但将图片放在中间。
\documentclass{report}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\geometry{letterpaper, margin = 1in}
\usepackage{newfloat}
\DeclareFloatingEnvironment[fileext = los, listname = {List of Schemes}, name = Scheme]{scheme}
\usepackage{graphicx}
\newcounter{compound}
\newcommand{\compound}[1]% #1 = label
{\refstepcounter{compound}\label{#1}Compound \thecompound}
\begin{document}
\begin{scheme}[htp]
\centering
\leavevmode\llap{\compound{test}:\qquad}%
\raisebox{-0.5\height}{\includegraphics[scale = 0.7]{images/Carbdiazosyn}}% center
\caption{Generation ...}
\label{carbdiazosyn}
\end{scheme}
\centering This references the compound index, \ref{test}.
\end{document}
