The latest citation data released by Thomson ISI in June 2007 reveal that PCCP's Impact Factor has risen by 15% to its highest ever value of 2.892.

We are also delighted to announce that PCCP's Immediacy Index* has also risen again to 0.866. This is the highest value for any journal that publishes primary research in the fields of physical chemistry and chemical physics for the third year running.

These impressive figures underline 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 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.
