| Description
| - Large-scale plasma was created in molecular gases (CO, CO2, N2, H2O) and their mixtures by high-power laser-induced dielectric breakdown (LIDB). Compositions of the mixtures used are those suggested for the early earth´s atmosphere of neutral and/or mildly reducing character. Time-integrated optical spectra emitted from the laser spark have been measured and analyzed. The spectra of the plasma generated in the CO-containing mixtures are dominated by emission of both C2 and CN radicals. A vibrational temperature of cca 104 K was determined according to an intensity distribution in a vibronic structure of the CN (B2.SIGMA.+.sub/sub.-.SIGMA.+g) violet band. For comparison, the NH3-CH4-H2-H2O mixture has been irradiated as a model of the strongly reducing version of the early earth´s atmosphere. In this mixture, excited CN seems to be significantly less abundant than C2.

- Byla vytvořena plazma v molekulárních plynech (CO, CO2, N2, H2O) a jejich směsích metodou vysoce energetické laserové jiskry. Složení použitých směsí odpovídalo rané atmosféře Země neutrálního a/nebo lehce redukčního charakteru. Byla změřena a analyzována časově nerozlišená spektra záření laserové jiskry. Ve spektrech plasmy, vzniklé ve směsích obsahujících CO, byla dominantní emise C2 a CN radikálů. Vibrační teplota kolem 104 K byla určena z analýzy distribuce intenzit vibronické struktury CN (B2.SIGMA.+.sub/sub.-.SIGMA.+g) pásu v UV oblasti. Pro srovnání byla ozářena směs CH4 - NH3 - N2 - H2O jako příklad silně redukčního typu rané zemské atmosféry. V této směsi byl mnohem menší výskyt excitovaných CN částic než C2. Experimenty s laserovou jiskrou v molekulárních plynech nebyly prováděny pouze ve statickém uspořádání, ale také v plynné trysce (gas-puff target) umístěné ve vakuové interakční komoře. (cs)
