Upper-state rotational constants for the ν4 band of chlorine nitrate

Abstract The upper-state rotational constants for ν 4 band of 35 ClONO 2 are A ′ = 0.40361(4), B ′ = 0.0923(4) and C ′ = 0.07532(4)cm -1 . These values were originally determined by modeling the band. A normal coordinate analysis was subsequently conducted as an independent check of these rotational constants.
