Theoretical Chemistry in theory and pratice
The theoretical chemistry is a very versatile and essential part of chemistry. Its applications range from information technology methods to the solution of chemical problems through the application of mathematics. It includes summarized the basic principles of chemistry, but the difficulties in, the simplest theories and allegations of chemistry with complex mathematical formulas to. Accordingly, this part of chemistry should not be underestimated, because issues of quantum mechanics, which appear even for people of the subject itself is too complicated, are branches of theoretical chemistry.
What is the role of theoretical chemistry?
Since most chemical processes have already been researched and analyzed, it is the task of theoretical chemistry to improve existing methods and applications and perfect. Main task of theoretical chemistry is the prediction of results from chemical processes. This does not happen by guessing or trial and error. Instead, programmers are here commissioned to write the basis of chemical and mathematical formulas, complex programs to say thus producing the results of the experiment with high probability. Used the common programming languages like C or Fortran, but increasingly, programming languages are the fifth and latest generation therefore like Prolog, Lisp, C + + used. Therefore, this type of chemistry is also called non-experimental chemistry, since only theoretical considerations are used to support the practical chemistry.An example of how theoretical chemistry can lead to application, the interpretation of movements of the individual atomic parts. The most famous description of this subject area is the Heisenberg uncertainty principle. This means that the electron, which orbits the nucleus like the moon, the earth can be made only limited trace. The better you know the position of the electron at a given time, the worse one can predict where that will go. On the contrary, one can indeed indicate the direction in which the electron is moving, but the place where that is, is not then be clearly specified. This is just one of countless descriptions, without which we today can not live on the technical level, as we do today. For only through this field, we can now understand chemical bonds, molecules, or other types of matter from the perspective of mathematics. The theoretical chemistry has made all this real for us.
