Quantum Chemistry Frequently Asked Questions

What is quantum chemistry? Quantum chemistry is quantum mechanics applied to chemistry.

What is quantum mechanics? Quantum mechanics is a physical theory used to describe the behavior and properties of microscopic particles like electrons, protons and neutrons in atoms and molecules.

How do you apply quantum mechanics to chemistry? There are several versions of Quantum Mechanics. The most basic theory, non-relativistic Quantum Mechanics is based on six postulates and one basic equation that describes the state of a systems: the Schrödinger equation. Applying Quantum Mechanics to chemistry means to solve the Schrödinger to study atoms and molecules.

Is quantum mechanics reliable? Quantum mechanics has so far never found to conflict with any experiment. There are problems when Quantum Mechanics is applied to black holes and the like, but as chemists: who cares about black holes?

What’s the goal of Quantum Chemistry? I am not sure how to explain this in two lines. My goal as a Quantum Chemist is to develop new methods to solve the Schrödinger equation. I am aiming at general methods that we will be able to apply to all types of molecules with the desired level of accuracy.
