Title: Evaluation of
thermodynamic properties of selected free radicals
Coordinator(s): Tibor
Bérces
Remarks: Of interest
to I.2, I.5, and VI.
Larger Project resubmitted and undertaken as 2000-013-1-100
Objective:
The aim is to collect, critically review and evaluate thermodynamic
properties of inorganic and organic free radicals involved in combustion
and atmospheric chemical processes. The evaluation will outline the
present status of the knowledge of the heats of formation and other
thermodynamic properties of free radicals. Initially, effort will
be concentrated on those key radicals for which different experimental
methods lead to consensus values. Subsequently, the project will address
the properties of free radicals for which no consensus has been reached.
Free radicals are the driving forces of atmospheric chemistry; they
initiate the processes leading to tropospheric pollution and stratospheric
ozone depletion. Chemical kinetics data bases used in modeling atmospheric
chemistry require evaluated thermodynamic data as critical input parameters.
These data are themselves usually derived from kinetics measurements
in the form of bond strengths or equilibrium constants. The proposed
new project is thus an adjunct to ongoing kinetics data evaluation
projects. It will provide data to those projects, and use data from
those projects. Because of the international scope and importance
of atmospheric chemistry, the project requires an international panel
of experts for its execution.
