WebSep 10, 2024 · Emission of Swan bands from carbon dimers was observed at the edge of nozzles only or across the whole nozzle radius with highest intensity in the arc center, depending on current and nozzle geometry. Furthermore, absorption of C Swan bands and CuF bands were found with the arc plasma serving as background radiator. WebIt is generally assumed that the 3 Π 0+u state has a minimum but no discrete absorption or emission has been observed, see Nathans, 1950. Child and Bernstein, 1973 predict a …
