Molecular Dynamics simulation of Pyrazole aqueous solution at 298.15, 303.15 and 308.15 K

Abstract

           M D simulation of Pyrazole aqueous solution at 298.15, 303.15 and 308.15 K was carried out by using OPLS force field from this simulation we calculate RDF of N-H… OH₂ and N…HOH type of interactions the results show that the hydration shell around N-H site at 5A⁰ is decade with increasing temperature and reformed at 10A⁰, so N site has two conserved hydration shells at approximate 4 and 6A⁰ respectively these are stable in this temperature range but the order and number of water molecules are varying with temperature specially the hydration shell at 4A⁰.
