Non trivial chiroptical responses: experimental and theoretical investigations
No full textIn the past few years, our two groups of research have been collaborating on a number of projects
dealing with the assignment of the absolute configuration (AC) of complex chiral molecules of phar-
macological interest in the disordered phase. [1] These studies have been mainly carried out by means of
electronic circular dichroism (ECD) spectroscopy and quantum mechanical (QM) calculations at the den-
sity functional theory (DFT) level of approximation. Particular attention has been payed to non-trivial
chiroptical responses due to conformational flexibility and solvation.
Beside these shared activities, some more specific research fields have been investigated too. In par-
ticular, the Bologna group has performed studies concerning the hyphenation of enantioselective HPLC
methods with detection systems based on ECD [2] and the characterization of biomolecular recognition
phenomena between drugs and target or carrier macromolecules. [3] The Salerno group has developed
some skills in vibrational circular dichroism (VCD) [4] and chiral NMR [5] spectroscopies, thanks to the
availability of a VCD spectrometer and previous studies concerning the non-linear response of molecules
exposed to radiation.

Collective dynamics in molten potassium: An inelastic x-ray scattering study
No full textThe high-frequency collective dynamics of molten potassium has been investigated by inelastic x-ray scattering, disclosing an energy/momentum transfer region unreachable by previous inelastic neutron scattering (INS) experiments. We find that a two-step relaxation scenario, similar to that found in other liquid metals, applies to liquid potassium. In particular, we show how the sound velocity determined by INS experiments, exceeding the hydrodynamic value by ≈30%, is the higher limit of a speedup, located in the momentum region 1<Q<3 nm−1, which marks the departure from the isothermal value. We point out how this phenomenology is the consequence of a microscopic relaxation process that, in turn, can be traced back to the presence of “instantaneous” disorder, rather than to the crossover from a liquid to solidlike response
