Some results of the study of a microwave discharge in heavy hydrocarbons are presented. Microwave energy is
introduced into a liquid hydrocarbon by using a coaxial line. The pressure above the liquid surface is equal to the atmospheric pressure.
The system is fed in argon through a channel in the center conductor of the coaxial line, so that the discharge is ignited in the atmosphere
of argon and hydrocarbon vapors. Emission spectra of discharge were studied in different liquid hydrocarbons. It was shown that the emission
spectra mainly contain different sequences of Swan bands, and possible radiation of other plasma components is on the noise level. Spectra
of plasma emission are presented for plasma in liquid n-heptane, nefras ะก2 80/120, and oil C-9, used for the production of chemical fibers.
The rotational (gas) and vibrational temperatures are determined by processing of observed spectra.
