"Vibrational predissociation spectroscopy of Ar-tagged, trisubstituted silyl cations" by Andrew F. DeBlase, et. al. is selected as an editors choice in Chem. Phys. Lett.

After a year of troubleshooting, our 7T Bruker ICR is functional once again, collecting high resolution spectra of electrosprayed organometallic catalysts and macromolecules.

Andrew DeBlase gives a hot topic talk at the Gordon Research Conference on Gaseous Ions in Galveston, TX: "A Bottom Up Approach to the Zundel Continuum: 3rd Order Anharmonic Treatment of Shared Proton Spectra"

Remarks by Professor Johnson featured in the February 25th edition of the C&E News article "Why SN2 Reactions Don't Work in Water"

http://cen.acs.org/magazine/91/09108.html#

Professor Johnson will be giving the plenary talk at the German Physical Society meeting in Hannover in March. We have recently added numerous experimental capabilities to the laboratory, including a new cryo-ESI source, two new Surelite EX pump lasers, and a visible laser for electronic spectroscopy interrogation. J. Robert Roscioli has taken a position at Aerodyne Research in Boston, MA.
