 Crossed
Beam Machine with H-Rydberg Tagging
Technique |
|
|
|
Our research interest is bimolecular
reactions in gas phase, using the
crossed beam in combination with the
high resolution H-atom Rydberg
tagging time-of-flight technique.
With this powerful technique, we
could get deep insight of elementary
chemical reactions exactly.

The
H-atom Tagging photochemistry
machine with Tunable VUV Laser |
|
|
|
|
We have developed a new experimental
method in our laboratory for studying
photochemistry using the high resolution
time-of-flight Rydberg tagging technique
combined with a broadly tunable VUV
radiation source as well as a tunable UV
source. This technique is also likely
applicable to the photochemistry of many
other molecular systems in the entire
VUV region that is important in the
atmospheric and interstellar chemistry.

Surface
photoreaction dynamics with
two-photon photoemission
(2PPE) technique |
|
|
|
We employ femtosecond time-resolved
two-photon photon emission spectroscopic
technique to investigate the lifetime of
excited resonance state of adsorbed
molecules on metals and semiconductors.

Surface
photoreaction dynamics with the
state-of-the-art
quadrupole mass spectroscopic
technique |
|
|
|
We are setting up a machine with the
state-of-the-art quadrupole mass
spectroscopic technique, low background
detection of H2. We will employ
nanosecond laser or femtosecond laser to
investigate the photoreaction dynamics
of molecular adsorbates on metal,
semiconductor and insulator surfaces.

Photodissociation
with slice imaging technique |
|
|
|
Photodissociation dynamics of
molecules plays a great role in the
atmosphere photochemistry and the
photodissociation studies are also
very important in understanding the
basic processes in the chemistry
reaction. In our experiment the
studied molecule intersects with the
photolysis laser beam to absorb one
or more photons to dissociate into
fragments.
