Comments: UV absorption cross sections were determined in between 230 and 380 nm as a function of temperature (269–298 K).
In addition, IR absorption cross sections were determined in the range 500 - 4000 cm-1. The overall photolysis quantum yield, Phi at 308 nm 
and 298 K. Phi(308 nm) was pressure dependent, ranging from (0.94 ± 0.14) at 75 Torr to (0.30 ± 0.01) at 760 Torr.
