A email titled "Invitation to submit to PMC Physics B"

Dear Dr Liu,
We would like to invite you to consider PMC Physics B for open access publication of your next article.
PMC Physics B is a 100% open-access peer-reviewed journal that publishes articles on condensed matter, atomic, molecular and optical physics, and the interfaces between these areas. We would like to draw your attention to a paper published recently:

Research article Electron excitation and energy transfer rates for H2O in the upper atmosphere Penny Thorn, Laurence Campbell, Michael Brunger PMC Physics B 2009, 2:1 (2 January 2009) Abstract Provisional PDF
The journal is published by PhysMath Central, an independent publishing platform from the team that created BioMed Central, the successful and pioneering biomedical open access publisher.
Submit your research to PMC Physics B and take advantage of an efficient online submission process, a rapid, high-quality peer-review service, and immediate publication upon acceptance. There are no color or page charges and no limits on the number of figures or embedded movies. You can even submit a preprint paper using just your arXiv id.
Further dissemination of your published work is encouraged by making the XML of the full text and MathML of formulae free to all for text or data-mining purposes.
To enable the journal to make all of its content open access, PMC Physics B will levy an article-processing charge for each manuscript accepted after peer review. This charge will be covered by your institution if it is a full Member of BioMed Central.
Please submit your manuscript via our online submission system. For more information about the journal, contact pmcphysb@physmathcentral.com or visit our instructions for authors.
