Data: table, diagram

Energy/Wavelength range: 235 - 390 nm

Resolution: 0.6 nm (FWHM)

Temperature: 298 K

Temperature dependence: yes

Pressure/Concentration: 

Phase: gas

pH:


Comments: The temperature dependence of the cross-sections was investigated over the range 333-243 K.
The spectra consist of a broad continuous absorption band with maximum cross-sections of (6.0±0.1) x 10-19 cm 2 molecule-1 for CF3I at 267 nm, (1.09±0.02) x 10-18 cm2 molecule-1 for CH3I at 258 nm, (1.18±0.04) x 10-18 cm2 molecule-1 for C2H5I at 258 nm and (1.21±0.07) x 10-18 for CH2ICl at 270 nm.
