Die Chinoxaline (II) und (III), die gegen DNS‐ und RNS‐Viren wirksam sind, werden aus den Diaminen (I) über die entsprech‐ enden Chinoxalinone durch Reaktion mit Phosphoroxychlorid erhalten.
This paper reviews two measuring methods of the ions and their results in low pressure plasmas, if spectroscopical methods are not applicable to this situation. The behaviour of ions in the positive column of a high current argon hollow cathode arc was studied in dependence of various plasma parameters with the help of a gridded probe and a quadrupole mass spectrometer. The obtained results were analysed with simple theoretical models and measured electron distribution functions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
