Abstract
Reflection second harmonic generation (SHG) has been applied for the investigation of the dielectric constant of a submonolayer of organic molecules adsorbed at silica/CH3CN interfaces. We show that the ratio of dielectric constants (εm,2ω/εm,ω) of the interfacial molecular layer can be obtained from the ratio of SHG intensities (I2ω45°-S,R/I2ωS-P,R), and using the ratio of dielectric constants the linear susceptibility (χ(1)) and polarizability (α) of solute molecules at resonant frequency can be evaluated.
