我已经获得了列表中所需的块(第 4 项),但我需要它与项目标签对齐。
\documentclass[11pt,twoside]{article}
\usepackage{enumitem}
\begin{document}
\section*{Valence Bond Theory (VBT)}
\textbf{Valence Bond Theory}: States that the overlapping of incompletely filled atomic orbitals leads to the formation of a chemical bond.\\
\begin{enumerate}[leftmargin=0.6cm,itemsep=0pt,label={\arabic*}.]
\item Covalent bond is formed by overlapping of atomic orbital, atoms should be very close.
\item Only half-filled orbitals with electrons of opposite spin overlap.
\item Overlapping must be $<$50\%
\item \begin{fleqn}
\begin{align*}
\text{Extent of Overlapping} &\propto \text{Strength of Bond}\\
&\propto \text{Bond Energy}\\
&\propto \dfrac{1}{\text{Bond Length}}
\end{align*}
\end{fleqn}
\end{enumerate}
\end{document}
给出的解决方案这里产生另一个错误的结果。
答案1
我建议您用单个环境替换嵌套的fleqn
/环境。我还建议您用替换。align*
aligned[t]
itemsep=0pt
noitemsep
\documentclass[11pt,twoside]{article}
\usepackage{enumitem,amsmath}
\begin{document}
\section*{Valence Bond Theory (VBT)}
\paragraph{Valence Bond Theory} States that the overlapping of
incompletely filled atomic orbitals leads to the formation of
a chemical bond.
\begin{enumerate}[leftmargin=0.6cm,noitemsep]
\item Covalent bond is formed by overlapping of atomic
orbital, atoms should be very close.
\item Only half-filled orbitals with electrons of
opposite spin overlap.
\item Overlapping must be $<$\,50\%.
\item $\begin{aligned}[t]

答案2
以下是两种选择:
\documentclass[11pt,twoside]{article}
\usepackage{enumitem}
\usepackage{nccmath}
\begin{document}
\section*{Valence Bond Theory (VBT)}
\textbf{Valence Bond Theory}: States that the overlapping of incompletely filled atomic orbitals leads to the formation of a chemical bond.
\begin{enumerate}[leftmargin=0.6cm,itemsep=0pt,label={\arabic*}.]
\item Covalent bond is formed by overlapping of atomic orbital, atoms should be very close.
\item Only half-filled orbitals with electrons of opposite spin overlap.
\item Overlapping must be $<$50\%
\item \abovedisplayskip=0pt\abovedisplayshortskip=0pt~\vspace*{-\baselineskip}
\begin{fleqn}
\begin{align*}
\text{Extent of Overlapping} &\propto \text{Strength of Bond}\\
&\propto \text{Bond Energy}\\
&\propto \dfrac{1}{\text{Bond Length}}
\end{align*}
\end{fleqn}
\item \begin{tabular}[t]{@{}l@{\;$\propto$\;}l}
Extent of Overlapping & Strength of Bond\\
& Bond Energy\\
& $\dfrac{1}{\text{Bond Length}}$
\end{tabular}
\item another item
\end{enumerate}
\end{document}
