Phosphorus mononitride is an inorganic compound with the chemical formula P N. Containing only phosphorus and nitrogen, this material is classified as a binary nitride. From the Lewis structure perspective, it can be represented with a P-N triple bond with a lone pair on each atom. It is isoelectronic with N 2, CO, P 2, CS and SiO.
The spectrum of a particular molecule is governed by the selection rules of quantum chemistry and by its molecular symmetry. Some molecules have simple spectra which are easy to identify, whilst others (even some small molecules) have extremely complex spectra with flux spread among many different lines, making them far harder to detect.

Phosphorus nitride refers to several chemical compounds of phosphorus and nitrogen: Phosphorus mononitride; Tetraphosphorus hexanitride; Triphosphorus pentanitride
PO is formed when phosphorus is burnt in oxygen or ozone. It is a transient molecule observed in hot flames, or can be condensed into noble gas matrix. [8] PO can be formed in an inert gas matrix in the photolysis of P 4 S 3 O, a phosphorus oxysulfide. [9] On Earth, phosphorus monoxide can be prepared for study by spraying phosphoric acid into a
Phosphorus dioxide (PO 2) is a gaseous oxide of phosphorus. It is a free radical that plays a role in the chemiluminescence of phosphorus and phosphine. [1] It is produced when phosphates are heated to high temperatures. [2] In the ground state the molecule is bent, like nitrogen dioxide, but there is an excited state that is linear. [1]
Mixed oxides of nitrogen (MON) are solutions of dinitrogen trioxide (N 2 O 3) in dinitrogen tetroxide/nitrogen dioxide (N 2 O 4 and NO 2). It may be used as an oxidizing agent in rocket propulsion systems. [1] Mixed oxides of nitrogen are produced by dissolving nitric oxide (NO) gas in liquid dinitrogen tetroxide. Nitric oxide reacts with ...
Protactinium forms mixed binary oxides with various metals. With alkali metals A, the crystals have a chemical formula APaO 3 and perovskite structure, or A 3 PaO 4 and distorted rock-salt structure, or A 7 PaO 6 where oxygen atoms form a hexagonal close-packed lattice. In all these materials, protactinium ions are octahedrally coordinated.
Phosphorus has several allotropes that exhibit strikingly diverse properties. [11] The two most common allotropes are white phosphorus and red phosphorus. [12] For both pure and applied uses, the most important allotrope is white phosphorus, often abbreviated WP. White phosphorus is a soft, waxy molecular solid composed of P 4 tetrahedra. This P
