Vincenzo Aquilanti (born December 12, 1939) is an Italian chemist, emeritus professor at the University of Perugia. Career He graduated in Chemistry with Vincenzo Caglioti and Giangualberto Volpi at Sapienza University of Rome in 1963, where he started his career of scientist. In 1967–1968 he had been working in Dudley Herschbach's group at Harvard University. At the University of Perugia from 1968, he became full professor of general and inorganic chemistry in 1980. He is emeritus professor at the Università degli Studi di Perugia since 2010. He had been invited professor at the Federal University of Bahia from 2012 to 2016. Currently, he is associated to the Matter Structure Institute of the National Research Council Research The scientific activity, documented by more than 430 papers (h-index 50), concerns experimental and theoretical aspects in the fields of radiation chemistry, of the ionic reactions in the gas phase, of elastic, inelastic and reactive collisions, between atoms and simple molecules of atmospheric and astrophysical interest, of quantum and semi-classical physical chemistry. His experimental activity was initiated in Rome in the Sixties, with the study of the role of the reactions involving ions in radiation chemistry and of the mechanisms of ion-molecule reactions. The construction in Perugia in the Seventies of an original experimental apparatus, where coupling the technique of crossed atomic and molecular beams with the spectroscopic emission detection has led to the discovery of phenomena of polarization and interference in atomic and molecular collisions. A variant of such an apparatus is still operative in Barcelona. In the 80s, through an original technique of magnetic analysis of type Stern-Gerlach for the orbital states of polarization of spin and electronic angular momentum of atoms, such as halogens (F and Cl), oxygen, sulphur, he has obtained an ample phenomenology on the interactions of these species by molecular-beams scattering. These interactions provide remarkable information on the initial phases of chemical reactions, that involve long range forces determined by their open shell structure. From the Nineties, following the discovery of effects of rotational alignment in molecules in supersonic expansions, he has established a technology for the study of collisions of aligned molecules, obtaining the characterization of intermolecular forces and of their anisotropy. In the last years, he is developing, in the Perugia, Trieste, Taipei and Osaka laboratories, experimental instrumentations for the study of the collisional origin of molecular chirality. The theoretical activity is being developed in parallel
