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.


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.
