Study design
- Light source:
- not specified
- Light spectrum: wavelength in nm:
- > 115
- Details on light source:
- To produce OH radicals a lamp emits flashlight with an energy of 2 J.

Results and discussion
Any other information on results incl. tables
- rate constant of reaction between o-chloronitrobenzene and OH radicals: 8.7 ( ± 0.6) x 10 -4 cm³/s
- this results in a tropospheric residence of 270 ( ± 20) days (assuming 5 x 10E5 OH-molecules/cm³)
- t1/2 = 135 days
