  2. Nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide

    Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO.It is one of the principal oxides of nitrogen.Nitric oxide is a free radical: it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula (• N=O or • NO).

  3. Biological functions of nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Biological_functions_of...

    Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of N O. In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [1] It is a powerful vasodilator with a half-life of a few seconds in the blood.

  4. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    A diatomic molecular orbital diagram is used to understand the bonding of a diatomic molecule. MO diagrams can be used to deduce magnetic properties of a molecule and how they change with ionization. They also give insight to the bond order of the molecule, how many bonds are shared between the two atoms.

  5. Peroxynitrite - Wikipedia

    en.wikipedia.org/wiki/Peroxynitrite

    Peroxynitrite can be prepared by the reaction of superoxide with nitric oxide: [1] [2] [3] NO + O − 2 → NO(O 2) −. It is prepared by the reaction of hydrogen peroxide with nitrite: [4] H 2 O 2 + NO − 2 → ONOO − + H 2 O. Its presence is indicated by the absorbance at 302 nm (pH 12, ε 302 = 1670 M −1 cm −1).

  6. Dinitrogen tetroxide - Wikipedia

    en.wikipedia.org/wiki/Dinitrogen_tetroxide

    Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide (NTO), and occasionally (usually among ex-USSR/Russian rocket engineers) as amyl, is the chemical compound N 2 O 4. It is a useful reagent in chemical synthesis. It forms an equilibrium mixture with nitrogen dioxide. Its molar mass is 92.011 g/mol.

  7. Linnett double-quartet theory - Wikipedia

    en.wikipedia.org/wiki/Linnett_Double-Quartet_Theory

    LDQ theory has seen great success in explaining the structures of open shell systems such as nitric oxide or ozone due to the additional degree of freedom associated with having two independent spin sets. In the cases of nitric oxide and ozone, the maxima of the electron density of the localised orbitals result in distributions which closely ...

  8. Unpaired electron - Wikipedia

    en.wikipedia.org/wiki/Unpaired_electron

    Unpaired electron. Periodic table with elements that have unpaired electrons coloured. In chemistry, an unpaired electron is an electron that occupies an orbital of an atom singly, rather than as part of an electron pair. Each atomic orbital of an atom (specified by the three quantum numbers n, l and m) has a capacity to contain two electrons ...

  9. Nitrogen compounds - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_compounds

    Nitrous oxide (N 2 O), better known as laughing gas, is made by thermal decomposition of molten ammonium nitrate at 250 °C. This is a redox reaction and thus nitric oxide and nitrogen are also produced as byproducts. It is mostly used as a propellant and aerating agent for sprayed canned whipped cream, and was formerly commonly used as an ...
