The β(11,0) band of NO was measured at high resolution (0.06 cm−1) by the vacuum ultraviolet Fourier transform spectrometer from Imperial College, London, using synchrotron radiation at the Photon Factory, KEK, Japan, as a continuum light source. Such resolution facilitates a line by line analysis of the NO β(11,0) band which yields accurate rotational line positions and term values as well as the photoabsorption cross sections. The molecular constants of the B(11) Πr2 level are found to be T0=55 983.203±0.017 cm−1, A=47.977±0.024, Bv=1.010 77±0.000 37 cm−1, Dv=(6.7±0.8)×10−6 cm−1 and AD=0.0438±0.0035 cm−1. The sum of the line strengths for all rotational transitions of the NO β(11,0) band is determined as 3.04×10−16 cm2 cm−1, corresponding to a band oscillator strength of (3.44±0.21)×10−4.
