Electronic structure calculations showed that introducing more pyrazine rings decreases the energy levels of the lowest unoccupied molecular orbitals (LUMOs) and should aid electron transfer. The number and the positions of the pyrazine rings greatly influence the molecular packing in crystals and hence ...
b Metal-insulator transition temperature TMIT and c ρ(300 K) of LaNiO3 films with different thicknesses and surface terminations. Open circles indicate that no MIT was observed in the temperature range studied. d DFT and e DFT + DMFT calculations of the DOS of the Ni 3d orbitals ...
Scientific Reports volume 7, Article number: 2237 (2017) Cite this article 4245 Accesses 39 Citations 1 Altmetric Metrics details Abstract The quantum mechanical description of the chemical bond is generally given in terms of delocalized bonding orbitals, or, alternatively, in terms of correlations ...
Similarly, in methylenephosphoranes the "parallel" conformation has a planar CH2, whereas a pyramidal CH2 corresponds to the "perpendicular" conformation. Finally, the nature of the P-O bond in H3PO has been established through the study of Foster and Boys' localized molecular Orbitals. 展开 ...
What is the maximum number of electrons which can occupy the orbitals represented by n = 3, l = 2? Quantum Numbers: The trajectories and most probable positions of electrons around the nucleus can be described by four quantum numbers. These are principal quantum numb...
The optimal number of iterations depends on the size of the database and can be approximated as sqrt(N). def grover_search(database, marked_items): n = len(database) num_iterations = int(round(np.sqrt(n))) # Create a quantum circuit with n qubits circuit = QuantumCircuit(n, n) #...
160K In this lesson, learn about electron subshells, and how electrons occupy these orbitals while they circle the nucleus. Know about orbitals and their shapes. Related to this QuestionAn orbital with the quantum numbers n =3, l =2, m_l =-1 may be fou...

The interaction of gas phase endohedral fullerene Ho3N@C80 with intense (0.1–5 × 1014 W/cm2), short (30 fs), 800 nm laser pulses was investigated. The power law dependence of Ho3N@C80 q+, q = 1–2, was found to be different from th
In the absence of electric fields, EADs are constructed in a quantum chemical spirit by the linear combination of Gaussian-type orbitals (GTOs) of surrounding atoms, preserving the overall rotational, translational, and permutational invariance of the system. However, an applied field can certainly ...
