Pendahuluan

Kimia Teori? Kimia Komputasi/Komputasi Kimia ◦ How does our modelling of intermolecular forces and potential energy surfaces yield a powerful understanding of natural systems at the molecular and ionic level ◦ The underlying physical laws necessary for the mathematical description of a large part of physics and the whole of chemistry are thus completely known, and the only difficulty is that the exact application of these laws leads to equations much too difficult to be soluble ◦ Computation is the use of digital technology to solve the mathematical equations defining a particular theory or model.
8
The term theoretical chemistry may be defined as the mathematical description of chemistry. The term computational chemistry is generally used when a mathematical method is sufficiently well developed that it can be automated for implementation on a computer. ◦ Note that the words “exact” and “perfect” do not appear in these definitions. Very few aspects of chemistry can be computed exactly, but almost every aspect of chemistry has been described in a qualitative or approximately quantitative computational scheme. The biggest mistake a computational chemist can make is to assume that any computed number is exact.
