# Free Online Quantum Chemistry Textbooks

Quantum chemistry is the application of quantum mechanics for explaining and predicting chemical behaviors. Much of the field of study centers around the “SchrÃ¶dinger equation for determining the energy levels of molecules and the molecules’ properties such as conductance, charge distribution, and reactivity”

This advanced chemistry subject falls under the umbrella of theoretical chemistry.

I was pleasantly surprised to find so many quality online materials that are being freely offered for students – I honestly didn’t think there would be so many quality textbooks available for chemistry students working at this level. The quantum chemistry textbooks listed here offer students alternative materials to standard print textbooks and a huge wealth of help for struggling students. Best of all, they are all available at not cost.

If you are an author, student or scholar who knows of any additional textbooks which I should include, please let me know.
