Natural Orbitals (NOs) are the unique orbitals chosen by the wavefunction itself as optimal for its own description. Mathematically, the NOs {Θ} of a wavefunction Ψ can be defined [1] as the eigen orbitals of the first-order reduced density operator Γ, (1) Γ Θ k = pk Θ k (k = 1,2,...)

Niobium monoxide is the inorganic compound with the formula Nb O. It is a grey solid with metallic conductivity. [1] NbO adopts an unusual cubic structure, similar to the rock salt structure but with some missing atoms compared to it, so that both niobium and oxygen atoms have square planar coordination geometries.

NBO 7.0 is the current version of the broad suite of 'natural' algorithms for optimally expressing numerical solutions of Schrödinger's wave equation in the chemically intuitive language of Lewis-like bonding patterns and associated resonance-type 'donor-acceptor' interactions.

In quantum chemistry, a natural bond orbital or NBO is a calculated bonding orbital with maximum electron density. The NBOs are one of a sequence of natural localized orbital sets that include "natural atomic orbitals" (NAO), "natural hybrid orbitals" (NHO), "natural bonding orbitals" (NBO) and "natural (semi-)localized molecular orbitals" (NLMO).

Banks have access to Norges Bank's settlement system (NBO) via the international SWIFT network or a system resembling a web-based banking application called NBO Online. Each bank has a main account (Real Time Mechanism, RTM, account), a l …

Niobium (V) oxynitrate is an inorganic compound with the proposed formula NbO (NO 3) 3. A single publication claims that niobium (V) oxynitrate is produced by the reaction of niobium pentachloride and dinitrogen pentoxide at 30 °C: [1] Nitryl chloride is produced as a byproduct.

Sep 17, 2010 · Overproduction of neuronal nitric oxide synthase (nNOS)-derived NO is detrimental during cerebral ischemia. Normobaric hyperoxia (NBO) has been shown to be neuroprotective, extending the therapeutic time window for ischemic stroke, but the mechanism is not fully understood.
