# One column equation in twocolumn document class

I am writing a paper (revtex4-1, reprint documentclass which I believe uses twocolumn) and need to have a long equation that needs to break the two column format. I've seen answers to this question using multicol but I can't use that class. So does anyone know how to do this from twocolumn class?

I have tried one way that makes the equation a figure but I can't get the alignment with the text correct.

Any help would be greatly appreciated.

The widetext environment changes the formatting from two-column to one-column to better accommodate very long equations that are more easily read when typeset to the full width of the page:

\documentclass[twocolumn]{revtex4-1}
\usepackage{lipsum}

\begin{document}

\lipsum[1]
\begin{widetext}
$a + b + c + d + e + f + g + h + i + j + k + l + m + n + o + p + q$
\end{widetext}
\lipsum[1]

\end{document}

I tried to put this code in a Elsevier two-column article but it doesn't work. It adds some strange text above and below (as you can even see in this example itself) the equation and stay only within one column. Any suggestions? –  Udita K. Jul 13 '13 at 3:07
