SUMMARY:Studying molecule-surface interactions using rotational orientatio
 n control of ground-state molecular beams - Gil Alexandrowicz\, Department
  of Chemistry\, Swansea University
DTSTART:20190509T150000Z

UID:TALK122032@talks.cam.ac.uk
CONTACT:Stephen Walley
DESCRIPTION:Performing quantum state selective experiments of molecule-sur
 face collisions provides unique insight into the interaction potential. On
 e particularly tricky molecular property to control and measure is the rot
 ational projection states\, i.e. the orientation of the rotational plane o
 f the molecule. Previous data was mostly restricted to photo-excited/param
 agnetic species.  In this talk\, I will describe the apparatus\, proof-of-
 principle experiments\, demonstrating control and measurements of the rota
 tional projection states of ground state hydrogen molecules[1]\, new exper
 imental results for H2 colliding with ionic surfaces\, and discuss the fut
 ure of this new technique in terms of studying interaction-potentials and 
 modifying the outcome of reactive molecule-surface collisions. \n\n[1] Nat
