Molecular Reaction Dynamics is a
subject between chemistry and
physics. It relies on sophisticated
experimental and theoretical
techniques to seek the essence of
chemical reaction on molecular
level, using the language of Quantum
Mechanics. It answers questions
about chemical reaction, such as:
What are the products in a given
reaction or photochemical process?
What is the distribution of the
quantum states of the product
molecules? In which quantum state a
molecule is most reactive? How does
the collision energy affect the
reactivity? Where does the energy go
in a reaction? Answers of these
questions are very significant to
deeply understand the variant
chemical processes in the nature,
such as atmosphere chemistry,
combustion process, life phenomenon
and interstellar chemistry.
During my scientific research career, I have
built a reflectron time-of-flight
mass spectrometer, an ion velocity-
mapping machine and a cavity
ring-down spectroscopic system, each
of them is the first one in China.
Since 2000, I have been studying the
dynamics of isotropic variant of H +
H2 → H2 + H reaction on a crossed
molecular beam apparatus that
employs the Rydberg-atom
time-of-fight detection scheme. The
research results have been published
in Nature and Science respectively.
