The large number of elastic and inelastic collisions which take place during supersonic gaseous expansions produce not only acceleration and internal cooling of molecules, but also their alignment or orientation. The collisional alignment of the rota

Experimental investigations on the collisional alignment of the rotational angular momentum, occurring in supersonic seeded beams and in drift tubes, have recently documented a strong dependence of the observed effects on the final molecular velocity

Two new techniques have been applied to the study of seeded atomic beams produced by expansion in vacuum. The first technique is a calculation of gas kinetic cross sections based on an improved Lennard-Jones potential. The second one is a new version

Relaxation and alignment of the rotational angular momentum of ethylene molecules are here shown to be induced naturally by collisions occurring in supersonic seeded expansions, which lead to generation of continuous molecular beams. Dependenes of th

Production, characterization and control of alignment degree of molecules are of importance for investigating in detail the stereodynamics of elementary processes involving elastic, inelastic and reactive events and also to prepare gas-phase species
