The structural chemistry deals with the interpretation of the physico-chemical properties of the substances at molecular level. It relies upon the general chemistry, applies the results of the quantum chemistry and provides for the theoretical background for the evaluation of the results yielded by the instrumental measurements of the analytical and organic chemistries.

This lecture note is based on mathematics, especially on the differential, integral, vector and matrix calculuses and on physics, especially on parts of electricity, magnetism and optics.
