Comments: Absolute absorption cross sections are determined for the three isomeric trichlorobenzenes in
the gas phase in the region from 33000 to 60000 cm-1, and relative absorption cross sections of
the tetrachlorobenzenes, pentachlorobenzene, and hexachlorobenzene are presented in the region
from 40000 to 60000 cm-1.
At 49780 cm-1 the absorption cross sections for C6H2Cl4 is sigma(max) = 2.13 x 10^-16 cm2 (value derived with the
assumption that SIGMA f = 1 (see original paper).
