### Please Make A Note: LaTeX: Vertical Spacing in Multiline Equations

Please Make A Note: LaTeX: Vertical Spacing in Multiline Equations: "\setlength{\jot}{12pt}"

Haha, I was searching if \vspace*{} worked or not in the align environment and stumbled across my friend's blog post. This works! However, for local entries I had to put yNot's suggestion from the comments where after the line breaks you put [12 pt], for example.

\begin{align}\setlength{\jot}{12pt}
\psi_{yyyy} = \alpha &R \left[ \psi_{yyt} + \left( y + \psi_y \right) \psi_{xyy} - \psi_{yyy} \psi_x \right] - 2 \alpha^2 \psi_{xxyy} \nonumber \\[12 pt] &+ \alpha^3 R \left[ \psi_{xxt} + \left( y + \psi_y \right) \psi_{xxx} - \psi_x \psi_{xxy} \right] - \alpha^4 \psi_{xxxx}
\end{align}
