Тетракетондиоксан (или 1,4-диоксан-2,3,5,6-тетрон) — это органическое соединение с формулой C₄O₆. Оксид углерода, который может быть рассмотрен как четырежды кетон диоксана. Он может так же быть рассмотрен как циклический димер оксирандиона^[англ.] (C₂O₃).

В 1998 году Паоло Страццолини и соавторы получили это вещество путём реакции хлорида (COCl)₂ или бромида оксалила (COBr)₂ с суспензией оксалата серебра (Ag₂C₂O₄) в диэтиловом эфире при −15 °C, и последующим испарением растворителя при низких температуре и давлении. Вещество устойчиво тогда, когда оно растворено в эфире и хлороформе при −30 °C, но разлагается с образованием смеси оксидов углерода (II) и (IV) при 0 °C^[1]. Устойчивость и конформации молекулы были также проанализированы теоретическими методами^[1].

Circular polarization

Polarization state The electric field vectors of a traveling circularly polarized electromagnetic wave. This wave is right-handed/clockwise circularly polarized as defined from the point of view of the source, or left-handed/anti-clockwise circularly polarized if defined from the point of view of the receiver. In electrodynamics, circular polarization of an electromagnetic wave is a polarization state in which, at each point, the electromagnetic field of the wave has a constant magnitude and ...
