Initially, models of chemical systems displaying oscillatory behavior were judged successful if they could show how such behavior was even possible. Recently, however, reaction mechanisms for chemical oscillators have been subjected to more stringent experimental tests. I examine strategies for model testing that flow from theoretical considerations, in particular, the types of feedback relations between chemical species required to produce oscillatory behavior in mechanistic models. These theoretical considerations allow chemists to work around important practical considerations such as an inability to (...) measure certain species in the experimental system. These sorts of testing strategies illuminate chemists' desiderata for a "good model.". (shrink)

I consider a way the concept of causation could be excised from chemical practice, suggested by Kitcher's view that causes are just a subset of unifying patterns which play a particular psychological role for us. Kitcherian chemistry is at first blush well equipped to handle explanatory tasks. However, it would force chemists to accept certain unifying patterns as explanatory, which they do not think are at all explanatory. This might head off some descriptive lines of enquiry and damage prospects for (...) the identification of potentially larger‐scale explanations. More important than this, to chemists, it could put them off from finding the explanatory patterns that are true—true because they get at the real structure of the chemical phenomena in the world.
