CH3Br + hv -> Products

" Table 52 lists the recommended absorption cross sections at 298K, taken from
Gillotay and Simon [567].  These authors measured the cross sections down to
210 K;  for < 210 nm the temperature effect is negligible.  Molina et al. [1106]
and Robbuns [1330] have also measured the absorption cross sections for this
molecule at room temperature;  the agreement among the three studies is very
good."
