Abstract
A newly designed two-dimensional corona-excited slit nozzle discharge is described and its first applications for direct absorption spectros copy of molecular ions in a supersonic expansion in the infrared (NO+) and far-infrared (N2H+). The results are discussed and it will be sho wn that under the conditions described, for N2H+ linewidths of 750 kHz and rotational temperatures of 12 K can be achieved.
