I want to achieve what the picture shows below. Basically, I want those two very long text lines to split into two lines shown below. My major problem is that if I keep the text in one line in flalign
, then the entire right-side text will shift to the left. Here is my code.
\documentclass[a4paper]{article}
\usepackage{mathtools}
\usepackage{nccmath}
\usepackage[margin=1in]{geometry}
\newcommand \widebox[1]{\setlength\fboxsep{6pt}\boxed {\enspace#1\enspace}}
\newcommand \dpartial[2]{\frac{\partial #1}{\partial #2}}
\newcommand \ddef[2]{\frac{d #1}{d #2}}
\newcommand \spac{\\[0.6em]}
\setlength\parindent{0pt}
\numberwithin{equation}{section}
\title{\vspace{-5em} QM Formula List}
\author{David}
\date{}
\begin{document}

\begin{flalign*}
&i\hbar \dpartial{\Psi}{t} = -\frac{\hbar ^2}{2m}\dpartial{^2 \Psi}{x^2}+V\Psi &&\text{Shr\"odinger Equation}\spac
&\widehat{p} = -i \hbar \dpartial{}{x} &&\text{Momentim Operator} \spac
&\widehat{H} = -\frac{\hbar ^2}{2m} \ddef{^2 \psi}{x^2} + V &&\text{Energy Operator} \spac

\end{flalign*}
