Reflection absorption infrared spectroscopy (RAIRS) was employed to follow the impact induced adsorption of 2,2-dimethylpropane (neopentane) on a Pt(111) crystal surface at 180 and 300 K. The 300 K spectrum, which we assign to a neopentylidyne species, is very simple with one major peak at 2960 cm(-1). The spectrum of the species formed at 180 K, which we assign as neopentyl, is more complex with a series of overlapping peaks between 3000 and 2840 cm(-1). We will present evidence for the assignments and chemistry of the impact induced species using the techniques of RAIRS and temperature programmed desorption (TPD).
