Weak Intermolecular Interactions

Utilizing dispersion-corrected density functional theory (DFT) calculations, we demonstrate the weak intermolecular interactions of phenylenediamine dimer (pdd) clusters, emphasizing the local lowest energy structures and decomposition of interaction energies by natural bond orbital (NBO) and atoms in molecule (AIM) analyses.

Td Dft

NEXAFS outcomes and TD-DFT calculations pertaining to H2TPP and H2TPP(F) demonstrate the electronic inertness of b1u porphyrin macrocycle 1s → π* excitations. In fact, corresponding excitation energies, but not their oscillator strength values, are substantially unaffected upon fluorination of Ph rings.
