Abstract :
In infrared-visible sum-frequency spectra, interference between nearby bands is important in determining the spectral shape. Using Langmuir monolayers consisting of lipids having oppositely charged headgroups, we studied the influence of sum-frequency signal from interfacial water on the spectral shape in the CHx region.
