Comments: Between 132.5 and 120 nm, continuous absorption, with some diffuse bands. 
Relatively sharp absorption bands at 137.1, 135.3, and 133.9 nm, which may be contributed by a Rydberg transition.
Between 147 and 163 nm, diffuse bands are superposed on a continuum, with maximum near 157 nm.
Continuous absorption between 163 and 185 nm, with a maximum near 166 nm.
