The spectra consisted primarily of a continuum with some molecular band structure which was found to originate from the molecules OH, PbO, NO & CHO. These molecular bands were more pronounced in the region 290 nm to 320 nm, but the radiating systems involved extend to shorter wavelengths. The source of the continuum radiation was not determined explicitly, but is not inconsistent with a CO + O recombinations mechanism. (Author) 收起
