Figure 7.
VR-SFG spectra of a self-assembled monolayer (SAM) of 1-mercapto-3-isopropyl sulfonate (MPSA) on Au (MPSA/Au), black; a film of C60-SB on Au (C60-SB/Au), blue; a film of C60-SB on ITO (C60-SB/ITO), red. The vibrational resonance is associated with the SO3 symmetric stretch. Polarization is ppp. Time delay between IR and Vis pulses is 0, 0.67 ps and 2.0 ps, respectively.
