QUADMARTS is an international researched networks (IRN) sponsored by the CNRS, the University of Rennes and other partner institutions, which is dedicated to new methods and applications for product determination in elementary reactions and photodissociation processes with applications at low and high temperatures for astrochemistry, atmospheric chemistry and combustion. In the last years, experimental devices as well as theoretical tools have been developed to quantitatively address the issue of product branching ratios under a large variety of physical conditions in the different scientific communities cited above. From an experimental point of view, quantitative information can be obtained by several approaches, including photoionization or electron spectroscopy combined with mass spectrometry, optical spectroscopy and microwave spectroscopy.
