“…Discussions on the necessity for high resolution measurements of NO have been presented in previous papers of the series on NO bands. [1][2][3] In these papers we describe how we combined high-resolution vacuum ultraviolet ͑VUV͒ Fourier transform ͑FT͒ spectrometry with synchrotron radiation by taking the Imperial College ͑IC͒ VUV FT spectrometer to the synchrotron radiation source at Photon Factory, KEK, Japan, where a suitable zero dispersion two-grating predisperser is available on beam line 12-B. ͑The predisperser is necessary to limit the bandwidth to a few nm in order to achieve acceptable signal-to-noise ratios, S/N.͒ We have used this combination of facilities to make ultra high resolution cross-section measurements of NO in the wavelength region 195-160 nm.…”

Application of a VUV Fourier transform spectrometer and synchrotron radiation source to measurements of. VI. The ε(0,0) band of NO

“…The resonance line of Hg I at 184.8 nm was used as the reference wave number in the previous papers. 1,3 However, in this wavelength region we have no convenient absolute reference. From the calibration constant in the previous papers, we estimated the uncertainty in the absolute values as 0.1 cm Ϫ1 .…”

Erratum: The application of a VUV Fourier transform spectrometer and synchrotron radiation source to measurements of absorption bands of NO [J. Chem. Phys. 115, 3719 (2001); 116, 155 (2002); 117, 10621 (2002); 119, 8373 (2003)]

“…However, four other papers were published without any absolute calibration. [3][4][5][6] In the first three of these the uncertainty in the absolute wavenumbers was given as 0.02 cm −1 but should have been given as 0.1 cm −1 ; in the fourth it was correctly given as 0.1 cm −1 . The use of overlapping spectra to carry the calibration from the Hg I line to both longer and shorter wavelengths is unfortunately limited by the fact that the NO spectra were recorded using a predisperser to limit the spectral bandwidth to a few nm; this was necessary in order to obtain adequate signal/noise ratios.…”

“…[1][2][3][4][5][6] These papers have reported line positions, term values, molecular constants, line intensities, and band oscillator strengths. A review of the wavenumber calibration of the spectra now shows that small corrections ͑less than 0.1 cm −1 ͒ should be applied to the line positions, and hence also to the term values, reported in four of these papers.…”
