How to solve the basis set error warning on ghost atom
WebJun 10, 2024 · As we can see we have 4 basis functions in total (two on each hydrogen). You wrote something about, you would expect that in the case of uncontracted that we would have ""[number of electrons]x[number of basis functions] matrix"". As we can see this is not the case. Right now our matrix is in the atomic basis. WebShort notations are used for basis functions of s, p and d shells. We use the label z^2 for the Lz=0 component of d function as the short name of 3z^2 - r^2. For example, after applying all the rules above, we have the following cc-pVTZ basis functions for carbon atom: Atom Id. Shell. scotty downrigger installation
