Abstract

Measurement and simulation of the Swan bands’ emission of the atmospheric pressure microwave discharge in liquid n-heptane with and without argon bubbling were carried out. Rotational and vibrational temperature of C₂(d³Π_g) state are determined. It is shown that the bubbling of argon does not change the rotational temperature. The reasons for the unchanged temperature and the possibility of using the rotational temperature as the gas temperature are discussed.
