All Hello, Sign in. When we perform calculations in chemistry we are normally concerned with using the most accurate data and exact equations to obtain an acceptable answer. There are two mathematical techniques, perturbation and variation theory, which can provide a good approximation along with an estimate of its accuracy. Within limits, we can use a pick and mix approach, i.e. However, there are times when we are justified in making approximations that make calculations easier or even possible at all. Physical chemistry is the study of how matter behaves on a molecular and atomic level and how chemical reactions occur. Methods in Physical Chemistry: Schafer, Rolf, Schmidt, Peter C.: Amazon.sg: Books. Perturbation theory is another approach to finding approximate solutions to a problem, by starting from the exact solution of a related, simpler problem. [LII, 846 Pages, Hardcover] Read More… These two handy volumes provide a valuable overview of the most … Compared to perturbation theory, the variational method can be more robust in situations where it's hard to determine a good unperturbed Hamiltonian (i.e., one which makes the perturbation small but is still solvable). Watch the recordings here on Youtube! Formulating and solving problems is a key skill needed for success in this branch of Chemistry, which has the reputation of being difficult because of its intrinsic mathematical nature. 1.
