- •
SHG signal recorded from a Si-SiO2/liquid interface with an adsorbed dye.
- •
SHG contributions from adsorbed dye species and solid surface are distinguished.
- •
These two contributions are out of phase by π/2.
- •
Interaction of N+ dye moieties with surface silanol groups is considered to be the primary driving force for adsorption.
