Abstract

An investigation of structural and dynamical properties of Ni2+ in liquid ammonia has been carried out via Quantum Mechanical Charge Field Molecular Dynamics. By extending the quantum mechanical region to include first and second solvation shell, a more realistic representation of the system was achieved yielding improved results on present computational facilities. The structural results obtained from the 16ps trajectory agree well with experimental investigations for various nitrogen-containing Ni2+ systems. Detailed analysis of mean residence time and vibrational properties highlights a rather flexible structure of the first and second shells compared to Ni2+ in aqueous solution.
