Abstract
The second harmonic generation from pyridine multilayers adsorbed on Ag(111) has been studied for the elucidating the structure of the adsorbed layers. An irreversible phase transition in the pyridine overlayers was observed when the pyridine film/Ag crystal is annealed above approximately 145 K. The phase transition is speculated to be from the formation of ordered domains in the pyridine multilayers.
