Computational Chemistry

Computational chemistry is a branch of chemistry that utilizes computer simulation and mathematical algorithms to solve complex chemical problems. It applies the principles of theoretical chemistry, particularly quantum mechanics and classical mechanics, to calculate and predict the structures, properties, and reactivity of molecules and materials. By creating virtual models of chemical systems, this field provides insights that can be difficult or impossible to obtain through laboratory experiments alone, serving as a powerful complement to traditional experimental work and accelerating the design of new drugs, catalysts, and advanced materials.
