The raw formula for the title is: 
```THE $1 ^{1}B^{+}_{u} \leftarrow 1 ^{1}A^{-}_{g}$ ABSORPTION OF JET-COOLED TRANS,TRANS-1,3,5,7-OCTATETRAENE```
An example of what this looks like is below.

The MathJax renders on browse lists, and item view, but not for the show-full-metadata page. It is assumed that on the full metadata view, a user should be able to access the "raw" text, not get rendered symbols from MathJax.
