Comments: The vacuum ultraviolet absorption spectra of the chloromethanes and three dichloroalkanes are given
with extinction coefficients in the 50000 - 90000 cm-1 region.
The absorption assigned as the sigma* <-- n begins at ~ 50000 cm-1 and extends to 60000 cm-1 with the maximum
at 56790 cm-1 (~ 176.09 nm). A second distinct region begins at ~ 60000 cm-1 and extends to 73400 cm-1 with a
maximum at 71480 cm-1 (~ 139.9 nm). The third distinct absorption is extremely intense (epsilon(max) = 40000 l. mol-1 cm-1
doublet at 75400 and 76900 cm-1.
