Hopefully, this will lead to SCF convergence. Then you can move on with optimizing the geometry or running the 6-31+G(D) job, again reading the initial guess from the checkpoint file.

Basis Sets; Density Functional (DFT) Methods; Solvents List SCRF WebConversion to atomic units is done by multiplication with a unit constant. This convention can be easily remembered with the following examples: When you say “this bond length is 1.5 Å”, the IOData equivalent is bond_length = 1.5 * angstrom. The conversion from atomic units is similar to axes labels in old papers.
