In this work, we put forward a theoretical explanation of a peculiar effect found very recently (A. Gonzalez Urena et al., Chem. Phys. Lett. 341 (2001) 495). They have observed the deflection of a beam of molecules posessing a permanent…
It is shown that a circular dipole can deflect the focused laser beam that induces it, and will experience a corresponding transverse force. Quantitative expressions are derived for Gaussian and angular tophat beams, while the effects…
