di Chimica e tecnologia delle Sostanze Biologicamente Attive, Università “La Sapienza”, 00185 Roma, Italy; 3Dipt. di Chimica, Università “La Sapienza” 00185 Roma, Italy Virtually all biological processes involve chiral molecules of appropriate shape and size maintaining suitable functionalities in specific positions. Their specific interactions with appropriate receptors is at the basis of chiral recognition and biocatalysis. The very complex molecules that make up living organisms, such as DNA, RNA, proteins and sugars, are all chiral. One of the most remarkable facts in biology is that the biomolecular chirality, be it in virus, in a primitive bacterium, or in a human brain cell, is everywhere the same. In recent years, considerable progress has been made in the study of weakly bonded molecular complexes between chiral molecules in the gas phase using laser spectroscopy combined with supersonic beam. The results of

these studies Amobarbital are particularly useful since they refer to isolated systems unperturbed by environmental effects and, therefore, directly comparable to theoretical predictions. Resonant Two Photon Ionization (R2PI) Spectroscopy, coupled with time of flight (TOF) mass spectrometry, on cooled complexes in supersonic beam is an excellent tool for investigating the structure and the specific intermolecular interactions in hydrogen-bonded clusters between chiral aromatic alcohols and a variety of solvent molecules, including chiral mono- and bi-functional alcohols, amines and water. Recently this methodology to the study of R-1-phenyl-2,2,2-trifluoroethanol has been applied. The interaction of polarized light with chiral systems has been selleck chemicals llc studied. The circularly polarized light of POLAR beamline at ELETTRA synchrotron experiments will be reported for some chiral molecules. E-mail: yeghis.​keheyan@uniroma1.
