Department of Chemistry Organizes a Scientific Course on the Emergence of Quantum Chemistry in Nature

The Department of Chemistry at the College of Education for Pure Sciences – University of Samarra organized a scientific course entitled “Reasons for the Emergence of Quantum Chemistry in Nature”, presented by Assistant Lecturer Reem Ibrahim Mahdi and Assistant Lecturer Rusul Rifaat Jameel.

The course presenters explained that the emergence of quantum chemistry arose from the scientific need to interpret atomic and molecular phenomena that classical chemistry failed to explain, particularly in the early twentieth century, when experiments showed that the behavior of atoms did not conform to traditional expectations.

Studies of the light spectra emitted by atoms, along with experiments on blackbody radiation and the photoelectric effect, demonstrated that energy is not transferred continuously, but rather in discrete quantities known as quanta. Classical theories also failed to explain how chemical bonds are formed and how electrons move within atoms and molecules.

Therefore, a new theory based on the principles of quantum mechanics was developed, employing wave equations such as Schrödinger’s equation to accurately describe electron motion. This contributed to significant advances in physics and mathematics and enabled scientists to calculate molecular properties, bond energies, and chemical interactions with greater precision.

This development paved the way for wide-ranging applications in modern chemistry, materials science, pharmaceutical industries, and nanotechnology, making quantum chemistry a cornerstone for understanding matter at the atomic and molecular levels.
