Molecular Beam Depletion: A New Approach
During 
the last years some interesting experimental results have been reported for experiments 
in N2O, NO, NO dimer, H2, Toluene and BaFCH3 cluster. The main result consists in the observation of molecular beam 
depletion when the molecules of a pulsed beam interact with a static electric 
or magnetic field and an oscillating field (RF). In these cases, and as a main 
difference, instead of using four fields as in the original technique developed 
by I.I. Rabi and others, only two fields, those which configure the resonant 
unit, are used. That is, without using the nonhomogeneous magnetic fields. The 
depletion explanation for I.I. Rabi and others is based in the interaction 
between the molecular electric or magnetic dipole moment and the 
non-homogeneous fields. But, obviously, the change in the molecules 
trajectories observed on these new experiments has to be explained without 
considering the force provided by the field gradient because it happens without 
using non-homogeneous fields. In this paper a theoretical way for the 
explanation of these new experimental results is presented. One important point 
emerges as a result of this development, namely, the existence of an, until now 
unknown, spin-dependent force which would be responsible of the aforementioned 
deviation of the molecules.
