A postdoctoral position in the area of state-to-state dynamics of chemical
reactions is available immediately in the laboratory of Professor James J.
Valentini. The emphasis of the project is on the elucidation of the
influence of "many-body" effects--those features that distinguish reactions
in which one or both reactants are polyatomic from the prototype atom +
diatom reactions. Current target systems are atom + polyatom reactions
like H + CH4 and H + CHCl3 as well as more complex systems. The
experiments rely on REMPI measurements--Doppler-resolved and distance-of
flight/position-resolved--to map the energy distributions of both reaction
products. Stimulated Raman excitation methods are used to vibrationally
prepare the reactant molecule, and laser photolysis creates the reactant
atom. Related studies focus on reactions in molecular clusters, where the
"many-body" effects are solvation-like. The experiments are complemented
by computational simulations of the dynamics of the reactions on realistic
model potential energy surfaces as an aid to interpreting the experimental
results.
Interested applicants should contact Professor Valentini via email, fax, or
mail, and arrange to have two letters of recommendation sent to him. The
position will remain open until a suitable candidate is found.
