Barbara J. Finlayson-Pitts, James N. Pitts Jr., in Chemistry of the Upper and Lower Atmosphere, Atmospheric chemistry is an exciting, relatively new field. It encompasses the chemistry of the globe, from polluted to “clean,” remote regions and from the region closest to the earth's surface, the troposphere (∼ 10–15 km), through the tropopause (∼ 10–15 km) into the upper Dynamics studies of atomic and molecular collisions are particularly important to the understanding of energy transfer and chemical reaction processes in gas-phase systems. Such studies affect the understanding of physical and chemical processes in a wide range of systems, including terrestrial and planetary atmospheres, interstellar clouds

Indication of atomic collision processes comes from the optical reflectance (sunlight reflected from the surface), optical emission from ionospheres and, for the Moon, from laboratory analysis of actual Atomic, Molecular, and Chemical Physics. The Atomic, Molecular, and Chemical Physics group focuses on interactions of atoms, molecules, electrons and photons at low temperatures and low energies. Our programs include both experimental and theoretical projects, many of which entail collaborations within and outside the ~kieran/bro/lframe6/nodehtml.

The emphasis is on the physics of the upper atmospheres of the earth and planets as well as astrophysics, including solar physics, the physics of planetary nebulae, and. Atomic and molecular data play a key role in many areas of science like atomic and molecular physics, astrophysics, nuclear physics, industry, etc.
[1,2,3,4,5,6,7,8,9].The interpretation of interstellar line spectra with radiative transfer calculations usually requires spectroscopic data and collision data (e.g., atomic parameters, cross sections, etc.) [10,11].The second essential step in the scientific method is analysis of the data, which usually involves a process of pattern recognition.
