“…Infrared Spectroscopy. Comparisons of vibrational FTIR spectra acquired from these same ultrathin polymer films at grazing incidence vs bulk coated polymer films also support film organization through differences regarding both vibrational peak position and relative intensity. ,26e Figure presents the FTIR spectral region with various C−F-active IR bands for a perfluoroalkyl-grafted polysiloxane monolayer on gold containing 74% grafted perfluoroalkyl chains. The transmission spectra of the bulk perfluoroalkyl-grafted polysiloxane film (Figure B) is nearly identical to that calculated for a randomly oriented perfluoroalkyl system 26d.…”

“…It may be, in part, as a result of the influence of a nonuniform distribution of the analytes ( i.e. the fluorine is all located “on top” of the monlayer, giving rise to the shortest possible path for the ejected electrons), or as a result of adventitious incorporation of fluorine-containing impurities into the monolayers. These possibilities were probed in the following studies.…”
