As far as I know, the &XAS_TDP module is unable to print configurational coefficient information to output file like &TDDFPT. You aim cannot be achieved without modifying the CP2K source code.<br /><br /><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Tuesday, June 10, 2025 at 2:55:43 PM UTC+8 qing zhou wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><p dir="auto">Hello everyone,</p>
<p dir="auto">I am currently performing XAS calculations for a periodic system and would like to conduct Natural Transition Orbital (NTO) analysis. My XAS calculations are performed using the &XAS_TDP section, employing the PBE functional with a 45% Hartree-Fock (HF) component, and the def2-TZVP basis set for the excited Fe atom. After completing the calculation, I successfully generated the molden file, cube files, spectrum file, and out file. However, when I attempted to perform NTO analysis using Multiwfn, the program reported an error after loading the out file, indicating that electronic excitation information was missing.</p>
<p dir="auto">I would like to ask for your advice: how should I configure the settings to ensure that the out file contains the necessary electronic excitation information? I have attached my inp and out files for reference.</p>
<p dir="auto">Thank you all for your responses!</p></blockquote></div>
