Fluorine emission spectrum

WebThe emission spectrum of fluorine has been investigated under high resolution in the region 4220-7510 A. The spectrum was excited by means of a low-frequency, high-voltage discharge in fluorine flowing through a sapphire tube. Rotational analyses have been carried out for 21 bands in this region. Nine of these bands, WebFluorine are Gases Fluorides are naturally-occurring components of rocks and soil. They enter the atmosphere through volcanic emissions and the resuspension of soil by wind. …
