Quantum Mechanics is the branch of chemistry and physics that deals with the interaction of matter and light.
Quantum Chemistry is the application of the principles of quantum mechanics on the structure of atoms and molecules and their interactions.
Computational Chemistry makes use of computers to assist in solving the equations of quantum chemistry.
Molecular Modeling brings the methods of quantum chemistry and the procedures of computational chemistry together to solve/model the complex chemical problems and processes.
