Abstract: | Deflection of a cold supersonic toluene beam seeded in He has been observed
when these molecules interact with both a static and a resonant oscillating
electric field. The toluene beam splits into two beams each one peaking at a
deflection angle of 1 degree towards the positive and negative direction of
the Stark field when the employed resonant frequency between the two Stark
levels of the toluene molecule is 1411 kHz. This deflection angle is about
four orders of magnitude higher than the value one would expect from the
toluene dipole moment and the employed RF field gradient. Different
hypothesis are suggested to explain the observed strong beam splitting
including the possibility of transverse beam interferences induced by both
the resonant RF field and the transverse uniform electric field. A
theoretical model is presented based on molecular beam interferences induced
by the resonant RF field which seems to account satisfactorily for the
present observations. |
