This paper details an experimental and theoretical investigation in which a simplified version of the molecular beam electric resonance technique is employed that requires the use of a C-field only. In the experiment the forward intensity of a NO beam is measured as a function of the frequency of the oscillating electric field over the 900-1460 kHz range. Specifically, the interaction of the NO beam with a radio frequency (rf) field of 1.12 kV/m amplitude and -610 kV/m (2) of gradient at the horizontal plane during 72 micros produces a series of oscillations in the transmitted beam intensity. The theoretical analysis shows how the interaction between a beam of NO molecules and both a static and oscillating rf field produces interferences in the forward beam intensity and how the observed interferences are due to superposition of molecular internal states. Furthermore, the interference model reproduces satisfactorily the observed beam intensity oscillations. The present technique could be useful for the development of new schemes to achieve coherent control of molecular processes using radiowaves.

“…The interaction of polar molecules with resonant RF electric fields is a subject currently investigated by our group using different experimental methodologies. − Thus, depletion spectra of molecular beams have been reported when such polar molecules interact with static and resonant RF fields. − More recently, beam splitting of 1.5 mm toward both the positive and negative direction perpendicular to the beam propagation axis of a supersonic toluene beam seeded in He was reported as a result of its resonant interaction with a RF electric field. The observed toluene beam splitting could be explained by the onset of molecular interferences induced by the resonant RF field…”

Interferences in the Transverse Profile of a Toluene Beam Induced by a Resonant RF Electric Field

In this work, the interaction of a supersonic beam of toluene diluted in He with a resonant oscillating RF field is investigated both experimental and theoretically. It is shown how the resonant field induces a peak structure in the transverse beam profile which can be explained by the onset of molecular interferences. Specifically, the interaction of a toluene beam of 0.12 eV of translational energy with a resonant RF field of 1.12 kV/m amplitude, and -610 kV/m(2) of gradient at the horizontal plane, during 160 micros produces a series of maxima in the transverse beam profile. The observed structure was satisfactorily reproduced by a quantum interference model based on the interaction of two coherent superpositions induced by the resonant RF field. It appears the present experimental technique could be useful to investigate the spectroscopy and dynamical behavior of coherent beams of polar molecules.

It was shown that the formerly observed beam depletion 1 was the consequence of the beam deflection under resonant conditions .…”

Interaction of Polar Molecules with Resonant Radio Frequency Electric Fields: Imaging of the NO Molecular Beam Splitting

2006

View full text Add to dashboard Cite

The interaction between a NO supersonic beam and a resonant radio frequency (RF) field is investigated using laser ionization coupled to imaging techniques. It is shown how the resonant interaction leads to a beam splitting of +/-0.2 degrees toward both positive and negative direction perpendicular to the beam propagation axis. This phenomenon is rationalized using a model based on molecular interferences produced by the action of the resonant RF electric field.
