In this paper, scanning tunneling microscopy (STM) images and tunneling spectra of H{sub 3}PMo{sub 12}O{sub 40} and Cs{sub 3}PMo{sub 12}O{sub 40} deposited on graphite surfaces were obtained in air before and after pyridine adsorption on arrays of these heteropoly HPAs, and the interactions with pyridine were probed at the molecular level using STM. The interactions were subsequently confirmed by infrared spectroscopy. These studies demonstrate the selective interaction of pyridine with acid sites in these arrays and the dramatic alteration of array structure which results from this interaction. 46 refs., 8 figs.
