Question: Provide an explanation of the Pople style basis set, 6-31G (d,p). How many (contracted) basis functions, and how many primitive Gaussian orbitals are there for a carbon atom? WebJun 19, 2024 · A feature of the Pople style basis sets is that the s and p orbitals are fused when possible into an SP orbital (also called "L" orbital). This means that the s and p GTO's from the same orbital have the same exponent, but different coefficients. This was done to reduce the cost of calculations.
