6The two levels x and w of Douglas, Howe, et al., 1961 are believed Barrow, Fry, et al., 1963 to belong to the same electronic state; v numbering uncertain. Rotational perturbations in both observed levels.

12Thermochemical value Colin and Drowart, 1962; agrees fairly well with values derived from the continuous absorption (D00 leq 4.84 ev) and from a short extrapolation of the vibrational levels of the E state (D00 = 4.81 eV) if dissociation into 1D + 1D and 3P1 + 3P1, respectively, is assumed.
13Ca1led z by Douglas, Howe, et al., 1961 and renamed C' by Barrow, Fry, et al., 1963; v numbering uncertain. Low J lines (J < 29) are weak or absent causing the headless appearance of the bands.
