Q-Chem: Quantum Chemistry Software for Large Systems

Introduction The 1998 Nobel Prize for Chemistry was awarded jointly to Professors Pople and Kohn for the development of computational methods in quantum chemistry and, in particular, for the development of density-functional theory (DFT). The award acknowledges the enormous strides that these men and their disciples have taken during the last three decades and celebrates the revolution in chemical philosophy and practice that their ideas have wrought.
