![]() ![]() If we try to increase the computations’ precision, the time they require grows as well - to the point that the solutions call for a great amount of time of supercomputers' operation.” The approximation methods work very well when we are describing the behavior of individual molecules, but in case of intermolecular interactions, the inaccuracy is too high. Quantum chemistry is the field of quantum mechanics that is dedicated to the approximate solution of this equation for chemical systems. ![]() It is impossible to solve it with high accuracy. ![]() “We have the Schrödinger equation that can be used to describe any quantum system, says Ivan Chernyshov, researcher at ITMO’s ChemBio cluster. The problem is that modern quantum chemistry methods aren’t enough to completely and precisely describe the characteristics of intermolecular interactions. The process of brewing tea, digesting our meals or the rigidity of a new type of plastic - this all depends on the manner of the interaction of specific molecules. From the chemistry standpoint, we all live in the world of perpetual intermolecular interactions. ![]()
