Mesure de dipôle électrique en phase gazeuse ; application aux agrégats et aux biomolécules

Abstract : This manuscript discusses permanent electric dipole measurements of gas phase molecules and molecular complexes. The permanent electric dipole characterizes the distribution of charges in the ground state of the molecule; it depends on the internal charge transfers and on the geometric structure of the system. Measurements were performed with a molecular beam deflection setup (analogue to the Stern & Gerlach experiment) coupled with a laser vaporization/desorption source. We have studied three categories of systems: fullerene-metal clusters, one excess electron alkali halide clusters and polypeptides.
