Title: Are two-component RIMP2-RICC2 calculations possible ?
Post by: vvallet on October 05, 2021, 04:21:21 PM

Is it currently possible to perform two-component RICC2 calculations ? I have seen that 2c auxiliary basis sets exist for RI-J and RI-JK for example def2-TZVP-2c, what about the auxiliary correlation basis sets? Shall one use the "standard" ones ?
Thanks for your tips

Yes, two-component RICC2 calculations are available.
The standard cbas should be sufficient. When in doubt, try first the de2-TZVP and then def2-QZVP and check, whether there is an effect.
