Abstract
The spectroscopic properties of As4S4 with pressure have been computed by the quantum mechanical XP-PCM method and by density functional theory periodic calculations. The comparison has allowed the interpretation of the available experimental data. By comparison of the two methods and with experiments, we show that the XP-PCM method is able to reproduce the same behavior of the periodic calculations with much lower computational cost allowing to be adopted as a first choice computational tool for a qualitative interpretation of molecular crystals properties under pressure.

Abstract
The reactivity of propene under high pressure has been investigated in the framework of Car-Parrinello molecular dynamics. Changes in structural and electronic properties due to pressure have been analyzed in systems with a density ranging from 0.855 to 2.151 g/cm(3). A ionic collective mechanism which leads to the formation of oligomers has been found by both spin restricted and spin polarized formalism. The maximally localized Wannier centers analysis has allowed us to characterize the addition scheme and to identify a Wannier center with a high spread value involved in the formation of the principal reaction products.
