| Abstract: | The inelastic electron tunneling spectroscopy (IETS) of semifluorinated hexadecanethiol junctions is theoretically studied.
The numerical results show that the C-F vibration modes of semifluorinated alkanethiol series can not be detected, and the
C-H stretching mode in IETS is related to the CH2 vibration. It is demonstrated that the Raman modes are preferred over IR modes in IETS, which is in good agreement with the
experimental measurements presented by Beebe et al. Nano Lett., 2007, 7(5): 1364].
