Examples 7.3.7 and 7.3.7 illustrate the setup for XAS calculations using TDDFT with SRC functionals and CVS. Example 7.13.2 illustrates XES calculation using TDDFT+MOM. Examples 7.13.2 and 7.13.2 illustrate TP-DFT calculations.
Example 7.120 This example shows a calculation of the XES spectrum of water using TDDFT+MOM and a short-range corrected functional.
