Property-optimized Gaussian basis sets for molecular response calculations Article (PDF Available) in The Journal of Chemical Physics (13) October with Reads. A general review is presented on the subject of basis sets used in ab initio molecular calculations. Both Slater-type and Gaussian-type basis functions are discussed from various view-points and their relative merits are appraised. A particular emphasis is placed on Cited by: A basis set in theoretical and computational chemistry is a set of functions (called basis functions) that is used to represent the electronic wave function in the Hartree–Fock method or density-functional theory in order to turn the partial differential equations of the model into algebraic equations suitable for efficient implementation on a computer.

Gaussian basis sets for use in correlated molecular calculations. V. Core‐valence Cited by:

Correlation consistent and augmented correlation consistent basis sets have been determined for the second row atoms aluminum through argon. The methodology, originally developed for the first row atoms [T. H. Dunning, Jr., J. Chem. Phys. 90, ()] is first applied to exponents for the polarization functions (dfgh) are systematically optimized for a correlated wave function (HF+1+2).Cited by: GAUSSIAN 09W TUTORIAL AN INTRODUCTION TO COMPUTATIONAL CHEMISTRY USING G09W AND AVOGADRO SOFTWARE Anna Tomberg [email protected] This is a quick tutorial that will help you to make your way through the first steps of computational chemistry using Gaussian 09W software (G09).File Size: 1MB.

Optimization with the larger basis sets gives the qualitatively correct water dimer geometry (figure 1A). However, some combinations of functional and basis sets yield geometries (figure 1B) containing two hydrogen bonds. Some of these optimizations converged to a transition-state (one imaginary frequency) resembling the 1A by: Basis sets2 Most methods require a basis set be specified; if no basis set keyword is included in the route section, then the STO-3G basis will be used. The following basis sets are stored internally in the Gaussian program (see references cited for full descriptions), listed below by their corresponding Gaussian keyword (with two exceptions):File Size: KB.
