computational chemistry - B3LYP Explained - Chemistry Stack …
In my inorganic chemistry class, we were introduced to computational chemistry. We are told to use B3LYP theory in the program, but we never actually learned any of the computation yet. Could anyone explain simply what B3LYP is and how it fits into the DFT equation that looks like

Computational Chemistry (Ab Initio), what should I study?
2016年2月5日 · Quantum chemistry. With a background you can now proceed to understand the conventional methods of quantum chemistry. For this I would recommend Modern Quantum Chemistry by Szabo and Ostlund. Courses to take: In addition to what was already mentioned above, many universities will also have quantum chemistry and computational chemistry courses.
computational chemistry - Why are basis sets needed? - Chemistry …
2016年9月25日 · We are taught about the different types of basis sets (extended, minimal, double-zeta, plane wave), but I do not think it is clear as to why they are needed. After all, it is possible to do computational chemistry without a basis set (see James R. Chelikowsky, N. Troullier, and Y. Saad, Phys. Rev. Lett. 1994, 72, 1240).
