Microwave discharge in the lunar dust simulant with the addition of ammonium carbonate for studying prebiological synthesis

Using a microwave discharge, plasma-dust clouds were obtained in an environment of gases and vapors that could have been present in the atmosphere of the early Earth. The source of Н$_2$О, NH$_3$ and CO$_2$ molecules were decomposition processes under the action of a discharge of ammonium carbonate added to the main material under study – the LMS-1D lunar dust simulant. The discharge emission spectra showed the appearance of molecular bands OH, NH, CN, C$_2$ in the plasma-dust cloud. By comparing the experimental and calculated contours of the bands corresponding to the electronic-vibrational transitions CN $(B^2\Sigma\to X^2\Sigma,\Delta\nu=0)$, the vibrational ($T_v$ = 5000 K) and rotational ($T_r$ = 2500 K) temperatures of CN $(B^2\Sigma)$ were found.
