(Left) Reaction path energetics
for reactant
CHD3 initially in the £h = 0 (black arrow) and
£h1 = 1 (red) vibrational states. The curve
represents schematically a cut through the
multidimensional potential energysurfaces
governing reactivity. The numbers in the
parentheses indicate the vibrational quanta
of the product pairs relevant to this study.
(Right) Two normalized REMPI spectra of the probed CHD2
products, with IR-on (red) and IR-off (black), at Ec
= 3.6 kcal/mol. Two product images, both with IR-on, are
shown for probing of the
 Q
and
 Q
bands, respectively. Superimposed on the images are the
scattering directions; the 0¢X angle refers to the initial
CHD3 beam direction in the center-of-mass
frame.

Congratulations to Dr.Szu-yuan Chen on receiving 2009
NSC Ta-You Wu Memorial Award.

The research group led by Dr. Kopin Liu show that
exciting the C¡VH stretching mode in the exothermic
reaction F + CHD3 not only leads to
unexpected products DF + CHD2 but also
slows the reaction rate. Their results published in
Science on July 17, 2009. This work has been
highlighted on the
C & EN (Chemical & Engineering News),
Chemistry World, and
Nature Chemistry website.
