“…The length of uniformity in setups based on the chopper solution is quite long, greater than 30 cm in most of the supersonic flows and beyond 50 cm for many of them . This length of uniformity in temperature and gas density corresponds to hydrodynamic times in the range of hundreds of microseconds, which is enough to perform the kinetic experiments at the concentration range of the co‐reactant employed .…”

“…Die Uniformitätslänge ist bei Verwendung eines Choppers recht lang, größer als 30 cm in den meisten Überschallflüssen und bei vielen auch über 50 cm . Diese Uniformitätslänge von Temperatur und Gasdichte entspricht hydrodynamischen Zeiten im Bereich von einigen 100 μs, was zur Durchführung der kinetischen Experimente im Konzentrationsbereich des eingesetzten Coreaktanten ausreichend ist .…”

“…Wie aus Abbildung ersichtlich, sind die Raumprofile von T 1 im Wesentlichen gleich und die mittlere Temperatur liegt innerhalb der statistischen Unsicherheit, was die Aufrechterhaltung der Qualität und Uniformität des Überschallflusses bestätigt. Ein weiteres Beispiel für einen gepulsten Fluss ist in Abbildung b dargestellt und eine umfassende Studie ist an anderer Stelle dargelegt …”

“…[26][27][28][29][30][31][32] Today this technique has reached a high degree of transferability and versatility owing to the development of different strategies to obtain stable, non-turbulent pulsed flows that reduce considerably the necessary pumping capacities, [33][34][35] and to the design of temperature-tunable de Laval nozzles. 36 Our interest in the reactivity of molecular ions in astrophysical and planetary media has led us to report recently on the rate coefficients and branching ratios of reactions of CN − / C 3 N − ions with the polar molecules HCOOH and HC 3 N over the [36-300] K temperature range. [37][38][39] To our knowledge, it was the first time the kinetics of bimolecular reactions involving a tetraatomic anion was revealed at low temperatures.…”
