Vamp(c)

Vamp is a sophisticated semi-empirical quantum mechanics package, which is input compatible with MOPAC. Vamp has been optimized to be highly numerically stable and extremely fast. Vamp is the only semi-empirical program with the Natural Atomic Orbital/Point Charge (NAO/PC) model for molecular electrostatic properties. The system can be used to calculate accurate dipole, quadrupole and higher moments and high quality Molecular Electrostatic Potentials (MEPs).

Vamp can be used to:

• Search and optimize transition states.
• Calculate spectroscopic properties, including ESR, NMR, IR and RAMAN frequencies.
• Solvent effects and solvatochromic shifts.
• Simulation of environments.
