The motion of neutral molecules in a beam can be manipulated with inhomogeneous electric and magnetic fields. Static fields can be used to deflect or focus molecules, whereas time-varying fields can be used to decelerate or accelerate beams of molecules to any desired velocity. We review the possibilities that this molecular-beam technology offers, ranging from ultrahigh-resolution spectroscopy using molecular fountains to novel crossed-beam scattering experiments. The ability to control the… 

Manipulation and control of molecular beams.

It was demonstrated that a detailed understanding of the influence of the external field on the energy level structure of the molecules was required for the manipulation of molecules with electric or magnetic fields.

State- and conformer-selected beams of aligned and oriented molecules for ultrafast diffraction studies.

Experimental approaches to the manipulation of large molecules, i.e., the deflection, focusing and deceleration using electric fields are introduced and how these methods can be exploited to spatially separate quantum states and how to select individual conformers of complex molecules are detailed.
