The limits to the assignments and analysis were imposed by as yet unresolved anharmonic resonances with the states of the next higher polyad of levels lying above 1200 cm–1, which affect the rotational states involved in transitions that would be measurable with non-vanishing intensities. Vibration-rotation spectra pertaining to the levels in question were studied in the regions 880–1150 cm–1 (the v5 and v8 fundamental bands), 550–750 cm–1 (the v9 = v10 = 1 <- v10 = 1 hot bands) and 250–400 cm–1 (the v10 = 3 <- v10 = 2 “superhot” bands). A simultaneous least-squares fit of both types of data provides their reliable but in the case of accurate rotational data not always fully quantitative reproduction.
