โฆ Synopsis
Forces measured between two molecularly smooth sohd surfaces separated by mert orgamc hqulds exhibit spatial oxlllations with penodlaty
equal to the size of the bquid molecules. Between five and ten osclllatlons are measurable. and their amphtude IS large compared with rhe conventIonal ran der Waals force.
