Title: Exploring Chemistry with Electronic Structure Methods (3rd ed.) – Is it still the "best" DFT bible, and where does it fit in 2026?
Body:
I’m looking to deepen my practical understanding of electronic structure beyond just clicking buttons in Gaussian/ORCA. Everyone keeps pointing to "Exploring Chemistry with Electronic Structure Methods" by J. B. Foresman & A. E. Frisch (3rd edition).
For those who have used both the 2nd and 3rd editions:
Is the 3rd edition worth the upgrade? I know it added significant content on DFT (range-separated functionals, dispersion), solvation models (SMD), and excited states (TD-DFT). Is the explanation of conceptual topics like exchange-correlation functionals actually clearer, or is it still mostly Gaussian "click-ops" with theory sidebars? Benefits of the PDF Format The PDF format
The "best" way to use this book: Do you treat it as a cover-to-cover read, or a reference for specific calculations? I find the examples (ozone, transition metals, solvent effects) incredibly practical, but the theory feels light compared to Szabo & Ostlund.
The PDF situation: I know the 3rd edition is still in copyright (Gaussian Inc., ~2015). There is no legal free PDF. That said, many labs have a site license. Is there a legitimate way to get an e-book (e.g., directly from Gaussian’s website, or a library perpetual access copy)? I want a searchable version, but I’ll buy a used hardcopy if that’s the only legal route.
Bonus: For someone running ORCA (not Gaussian), is this book still 90% useful? The input file syntax differs, but the concepts of basis sets, population analysis, and opt+freq seem universal.
Current stack: Jensen's "Introduction to Computational Chemistry", Cramer's "Essentials of Computational Chemistry". Missing the practical "push this button, but here’s why" guide.
Thanks!
Optional follow-up comment for the "best" angle (if you want to add it):
Clarifying "best": I don’t mean best = cheapest (or free). I mean best = clarity + practical examples + minimal errors. The 3rd edition fixed the known issues with the 2nd (e.g., confusing discussion of MP2 spin contamination). So if you have a PDF of the 2nd edition lying around, don't use it for DFT—it's outdated. The 3rd is genuinely better.
The 3rd edition is tightly coupled with Gaussian 09, arguably the most stable and widely adopted version of the software in history. While Gaussian 16 exists, G09 remains the industry standard for many research groups due to its reliability. This book does not just list keywords; it explains why you use SCF=Conver=9 or Integral=Grid=UltraFine.
When users search for "exploring chemistry with electronic structure methods 3rd edition pdf best", the word "best" carries multiple connotations. Let us unpack what the community actually wants.
The book uses a "hands-on" tutorial style. Each chapter starts with a chemical question (e.g., "Why is benzene stable?") and walks you through building the molecule, setting up the input file, running the job, and interpreting the output. The 3rd edition adds extensive sections on visualizing results with GaussView 5.0. setting up the input file
