Quantum chemistry computer programs

Quantum chemistry computer programs are programs that help scientists do calculations about how atoms and molecules interact with each other. They can be used to help predict how different molecules will react with each other and to simulate chemical reactions. The programs use the theories of quantum physics to figure out what will happen when atoms and molecules come together. They help scientists understand the behavior of molecules better so that new molecules can be created for different purposes.
