Abstract

Classical electromagnetic theory has been used to quantitatively assess the effects of various experimental parameters on the sensitivity of IR-ERS for organic monolayers at liquid/solid (L/S) and gas/liquid (G/L) interfaces. Conditions varied at the G/L were angle of incidence and polarization. Additional conditions examined at the L/S, located in a thin-layer cell (TLC), were solution layer thickness and cell window material. The effects of these variations on sensitivity were determined for a model system consisting of a 30 A layer of C19H39 alkyl chains (C19) at H20/Au and air/H20.
