PCCP's latest 10th Anniversary Article is a Perspective article that, in historical retrospective, describes the development of the celebrated Landau-Teller (LT) model of 1936 for vibrational-translational energy exchange in collisions of an atom with a diatomic molecule. The article goes on the exemplify the usefulness of this approach to this day. 

The article was written by Juergen Troe and Evgueni Nikitin. Juergen Troe is professor of physical chemistry at Göttingen University and director at the Max-Planck Institute for Biophysical Chemistry at Göttingen, both in Germeny. He is currently a member of the PCCP Advisory board and has previously served as Chair of the PCCP Editorial Board. 

Troe is a prolific PCCP author and keen supporter of the journal. 'Several of our articles appeared in PCCP, the journal which is so close to my heart since my days as Editorial Chairman. With delight I saw PCCP growing up to its present stunning success,' he said. 

Troe and Nikitin have worked together over a number of years. 'The present retrospective from Nikitin's side is an homage to the great Landau and includes a series of improvements which make collisional energy transfer theory more correct and more "understandable". From my side, it is a testimony for more than 40 years of friendship and most enjoyable collaboration with Nikitin,' said Troe.
