- Аннотация: Emission spectra of microwave discharge in liquid hydrocarbons (hexane (C6H14), n‐heptane (С7Н16), decane (С10Н22), pentadecane (C15H32), cyclohexane (С6Н12), toluene (С6Н5–СН3), ortho‐xylene (С6Н5–(СН3)2), and petroleum solvent nefras S2 80/120 [mixture of light hydrocarbons with boiling temperature ranging between 33°C and 205°C]) were studied in the range of wavelength 200–700 nm. The pressure above the surface of the liquid was equal to the atmospheric pressure. It was shown that in the spectra measured in aromatic hydrocarbons (toluene and ortho‐xylene) the sequence of the Swan band with Δυ =0 was overlapped with the molecular emission band with a maximum at 511 nm never observed before. Analysis of known data allowed us to hypothesize that this emission can be attributed to the emission of linear carbon cluster C5 (transition C5( Πu X Σu)). This cluster was previously observed only in absorption. Rotational temperatures determined by modeling of the sequence Δυ=−1 of the Swan band were equal to 2,000± 300 K for all studied hydrocarbons.
