Web17 jan. 2024 · Abstract. Obtaining accurate ground and low-lying excited states of electronic systems is crucial in a multitude of important applications. One ab initio method for solving the Schrödinger ... Weblow-lying excited states for the above systems are calculated for correlated PPP model Hamiltonian, keeping the DMEV basis to be 500 for TTA. We first summarized the five low-lying singlet excited states in A and B subspaces in Table 1 for TTA. The ground state (gs) singlet 11A(S 0) energy is set to zero,

WebThe vertical excitation energies are calculated for the three lowest excited states of HO2 and the HO2–H2O, HO2–HONO, HO2–HONO2, and HO2–HO2NO2 complexes. The first excited state of each complex is found to be similar to HO2, but generally shifted from that of the HO2 monomer. There is also a dependence of the shift on the binding energy of … Web26 dec. 2024 · For the α-phase, the low-lying singlet states clearly reside mostly on one of the perylene dimers, with some smaller contributions found on neighboring dimers along … WebTo move one step forward in the comprehension of aromaticity in excited states, in this work we analyze the electron delocalization and aromaticity of a series of low-lying … hope ramafola
