The latest citation data released by Thomson ISI in June 2008 reveal that PCCP's Impact Factor has risen by over 15% to its highest ever value of 3.343.

PCCP is the only physical chemistry journal to show such a significant increase this year and as a result PCCP's Impact Factor has now overtaken that of some of its major competitors.

This impressive trend underlines the continuing success of PCCP. Coupled with exceptionally fast publication times, which are significantly faster than others in the field, this news reinforces PCCP's position as the journal of choice for publishing cutting-edge research of the highest quality in physical chemistry, chemical physics and biophysical chemistry.

We are also delighted to announce that PCCP's Immediacy Index* has also risen again to 0.883. This is the highest value for any journal that publishes primary research in the fields of physical chemistry and chemical physics for the fourth year running.

We would like to thank our authors, referees and readers for their continued support.

* The Immediacy Index is a measure of how topical and urgent the papers published by a journal are. The Immediacy Index is calculated by dividing the number of citations to articles published in a given year by the number of articles published in that year.
