Experiments were performed on the lateral transport kinetics of wettin
g layers. Optically excited surface plasmons were used to study both t
he spreading behaviour of silicon oil and the equilibration dynamics o
f ethanol. The precursor film profiles of silicon oil were found to ag
ree well with the theory of viscous flow of nonvolatile liquids. For e
thanol, evaporation effects and viscous transport could be observed se
parately. Apparently, the viscous transport is suppressed by almost tw
o orders of magnitude. Possible explanations are discussed.
