Electronic structures and stabilities of endohedral metallofullerenes TM@C34 using DFT approach

Theoretical study of the electronic structure using, Density Functional Theory (DFT) calculations at the B3PW91/6-31G (d) level of theory have been employed to the TM@C34 (TM =Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) in order to investigate the geometries, electronic structures, binding energies, linear polarizability ⟨Δ ⟩, first order hyperpolarizability ⟨ ⟩, natural […]

Experimental and theoretical electronic absorption spectra, optical, photoelectrical characterizations of 1, 2, 3-Thiazaphosphinine and 1, 2-Azaphospholes bearing a chromone ring: Solvatochromic effect and TD/DFT approach

Geometry, global energetic and dipole moment of the studied structures 1-4 in the ground state are calculated using the DFT/B3LYB/6-311++G (d,p) level of theory.  It has been uncovered that compounds containing 1, 2, 3-thiazaphosphinine and 1, 2-azaphospholes bearing a Chromone ring structure displays noteworthy biological properties. The studied compounds 1-4 are non-planar, as indicated from […]
