Low power microwave discharge

In studies of the interaction of fluorine atoms (produced in a low power microwave discharge through NFj or CF in argon carrier gas) with CO in an argon matrix (products rapidly quenched at 14 K), prominent infrared absorptions appeared characteristic of COFj, in addition to those of [COF]- [1021,1022],... 

Souter et al. [1997SOU/KUS] have identified the four gaseous thorium hydride species ThH (n = 1 to 4) by examining the IR spectra of the products condensed from the reaction of laser-ablated thorium with H2(g) in solid argon matrices. In some experiments, a discharge was passed through the Ar-H2(g) mixture, using a low-power microwave...

For some elements such as arsenic and selenium, which have their main atomic absorption wavelengths lying on the edge of the vacuum UV, the performance of hollow cathode lamps is often poor, the lamps displaying low intensity and poor stability. This, plus the search for more intense sources for AFS (see Chapter 1, section 10), resulted in the development of microwave-powered electrodeless discharge lamps (EDLs) as spectral line sources towards the end of the 1960s.3-5...
