✦ Synopsis

In order to perform the analysts of fluorine in Grimm-type glow-discharge emission specu-ometry, the specwa of flumine emitted by a neon as well as an argon plasma were investigated. While it was hard to detect fluorine emission lines ia the argon plasma, not only the atomic lines but also the ionic lines were observed in the neon plasma. The neon plasma should therefore be employed for fluorine analysis. It was suggested that the excitations of fluorine could be prima~y anribmed to eollisic~ml energy transfer from neon species having Iarge internal energies.
