Abstract:New spectrograms of CO below 1200 Å reveal that emission bands terminating on the high energy E01Σ+ and 1Π states plus most of the previously reported unidentified emission bands of CO actually originate from molecular nitrogen. Four new emission band systems in CO, tentatively identified as V1Π-X1Σ+, W1Π-X1Σ+, Y1Σ+-X1Σ+, and Z1Σ+-X1Σ+, have been observed. The corresponding Tv0′s are 98917, 102804, 99963, and 105724 cm?1, respectively.
