PM-IRRAS spectra. (a) MtCK at the air-buffer interface (thin gray curve). (b) CL monolayer in the absence (dotted gray curve 1) and in the presence of mtCK (dashed gray curve 2), difference spectrum of mtCK (i.e., CL in the presence of mtCK minus CL) (bold gray curve 3). (c) PC/PE/CL (2:1:1) monolayer in the absence (dotted black curve 1) and presence (dashed black curve 2) of mtCK, and difference spectrum of mtCK (i.e., PC/PE/CL (2:1:1) in the presence of mtCK minus PC/PE/CL (2:1:1)) (bold black curve 3). (d) Spectrum of mtCK at the air-buffer interface (thin gray curve 1) and difference spectra of mtCK at the CL or PC/PE/CL (2:1:1) buffer interface (bold gray curve 2 and bold black curve 3, respectively); the overlaid spectra correspond to curve 1 in a and curve 3 in b and c, and are presented on a common scale.
