| COMMENTS: | The output of a stable 30W deuterium (D2) lamp light source was collimated and directed through a jacketed 90.4-0.3 cm single-pass absorption cell, and the beam exiting the cell was focused onto the entrance slit (150 μm) of a 0.25m monochromator (∼1 nm resolution) and detected using a photomultiplier tube (PMT)
Parameterization of the temperature dependence valid over the wavelength range 192.5 to 235 nm for
temperatures between 230 and 323 K
ln (σ(λ,T)) = ∑i Ai λii + (T - 296) ∑i Bi λii with the following parameters Ai and Bi:
