The goal of this study was to determine the primary algebraic structures which describe the catalytic system in terms of observables. The sole experimental input to the identification is a matrix of in situ spectroscopic data A and a matrix of initial moles N0. Subsequently, we determine (1) the number S of observable species and their characteristic pure-component spectra a, (2) the moles of all observable species N, (3) the number R of reactions present and their reaction stoichiometries υ, and finally (4) the extent of reactions ξ. Meaningful extraction of such algebraic system information (an inverse algebraic problem) is a prerequisite to subsequent detailed kinetic modeling (an inverse kinetics problem). The methodology is successfully applied to this homogeneous transition-metal-catalyzed hydroformylation reaction. The methodological development has clear implications for exploratory studies of new catalytic systems (so-called "gray" reaction systems), in which only in situ spectroscopic reaction data and knowledge of the initial amounts of reagents put into the reactor/system are available. © 2003 Elsevier Inc.
