SFG spectra of polymer-ACM crystal interface with crystals grown from a supersaturated solution on: A) PMMA with PPP polarization combination, B) PMMA with SSP polarization combination C) PBMA with PPP polarization combination, D) PBMA with SSP polarization combination. (The polarization combinations are ordered sum frequency, visible, infrared.) The normalized IR absorbance of the PMMA and PBMA films are overlaid in blue and red respectively.
