 Becke, along with his co-researcher John Perdew, demonstrated that DFT could be an effective tool in quantum chemistry as well, where it is used to describe the structure and energetics of molecules.He developed a valuable computational technique (NUMOL) which allowed a new level of precision.His work has led to advancement in many areas of chemistry and physics, where his methods are used to calculate the molecular properties of large and complex molecular systems with greater accuracy.
