A solid, methodical survey of computational chemistry that earns its place on the shelf, though it too often explains the machinery without quite interrogating its limits.
Frank Jensen’s Introduction to Computational Chemistry is, in essence, a competent guide to the field’s standard toolkit: electronic structure theory, basis sets, molecular mechanics, molecular dynamics, and the usual parade of approximations that make the subject usable. I found it strongest when it is most disciplined — when it lays out the formalism clearly, tracks notation carefully, and resists the popular temptation to pretend that computational chemistry is merely a button-pressing exercise. For a reader who wants the architecture of the subject rather than anecdotes, this is a serious and generally reliable book.
That said, I should not overpraise its neatness. The book’s great virtue — its systematic progression — is also its principal limitation. It can read like a carefully machined syllabus, and in places the prose is so compressed that key conceptual tensions are passed over just when they deserve scrutiny. Approximations are described with admirable economy, but sometimes without enough emphasis on what they cost in practice: basis-set incompleteness, functional dependence, electron-correlation errors, and the perennial problem that “good agreement” may conceal compensating failures. A beginner may come away knowing what methods exist, yet not fully appreciating how fragile their apparent success can be.
I also think the treatment of modern practice is only partly satisfying. The book is strongest on the established core of quantum chemistry, but newer computational habits — the realities of large-scale modelling, statistical sampling, and the practical interpretation of noisy or dataset-driven results — are less vividly integrated. Where it discusses algorithms and scaling, it does so competently, but not with the sort of critical edge one would hope for in a text claiming introduction rather than catechism. In a field where method selection is often more consequential than derivation, I wanted a sharper hand on the trade-offs.
Still, Jensen writes as someone who understands that computational chemistry is built on controlled compromise, not magical exactness, and that is worth a good deal. I respect the book’s seriousness, its technical discipline, and its refusal to indulge in hand-waving. It is not an inspired book, and it is not the last word on the subject, but it is a sound one: the kind of text from which a diligent reader can actually learn the structure of the field, provided they are prepared to do some of the conceptual labour themselves.
Who should read this
I would recommend it to advanced undergraduates, beginning graduate students, and chemists who need a structured re-entry into the subject. Those seeking a more interpretive, critical discussion of what computational results really mean will need supplementary reading.
A personal note from Lindgren
I trust this book more than I enjoy it — which, in computational chemistry, is often as much praise as one can reasonably give.
