Proton Quantum Effects in H3_3S Electronic Structure: A Multicomponent DFT study via Nuclear-Electronic Orbital Method

This study utilizes Nuclear-Electronic Orbital DFT to demonstrate that while nuclear quantum effects significantly stiffen S-H bonds and alter phonon properties in high-pressure H3_3S, their direct impact on the electronic structure is minimal, indicating that the observed isotope effect on the critical temperature arises primarily from phonon changes rather than electronic modifications.
