Knowledge and Historical Background

"Introduction to Computational Chemistry" by Frank Jensen has been a leading textbook in the field since its first publication in the 1990s. Jensen, a professor at Aarhus University, developed this text to provide chemists with a practical introduction to computational methods that were becoming increasingly important in chemical research.

The book emerged during the computational revolution in chemistry, when advances in computer technology and quantum mechanical methods made computational chemistry accessible to experimental chemists. Each edition has incorporated new developments in algorithms, software, and computational methodologies.

Teaching Philosophy

The textbook emphasizes practical understanding of computational methods rather than mathematical derivations. It focuses on helping chemists understand what computational methods can and cannot do, how to choose appropriate methods for specific problems, and how to interpret computational results critically.
