| COMMENTS: | The experimental apparatus consisted of a light source, either a 30 W deuterium (D2) lamp or low-power Hg (184.95 nm), Zn (213.856 nm), or Cd (228.802 nm) atomic lamps, a jacketed Pyrex absorption cell, a 0.25 m monochromator with a photomultiplier tube (PMT) detector used with the D2 light source, or a photodiode detector used with the atomic light sources
The wavelength of the monochromator was calibrated using the Hg, Zn, and Cd lamp output to
±0.1 nm, and the measurements were made at a spectral resolution of ∼1 nm (FWHM)
Parameterization of the temperature dependence valid over the 190−230 nm wavelength range and 216−296 K temperature range:
log10 (σ(λ,T)) = ∑i Ai (λ - 200)i + (296 – T) ∑i Bi (λ - 200)i with the following parameters Ai and Bi:
