是否可以使用 TeX 构建谱线？

我想演示光谱线图中的变化。我想知道 TeX 是否能够生成光谱线图。我知道它在能级图方面的功能非常有用。提前致谢。

答案1

虽然，你已经解决了你的问题。这是一个使用 pgfplots 的相对简单的解决方案：

\documentclass{article}

\usepackage{pgfplots}
\pgfplotsset{compat=newest}

\begin{document}
    \begin{tikzpicture}
        \begin{axis}[width=8cm, height=5cm,
            xlabel=$\lambda$ (nm), ylabel=Intensity (a. u.), 
            ytick = \empty,
            xmin = 300, xmax=700, ymin = 0
        ]
        \addplot[ycomb, variable=\t, samples at={3,4,...,11}]
            (({364.6*t^2/(t^2-4)}, {1/t});
        \end{axis}
    \end{tikzpicture}
\end{document}

这里计算的值和强度计算只是一个野客，但你当然也可以绘制数据点。

和技巧只是为了好玩！
