Comments: The absolute absorption cross sections of (CH3)2COO under a jet-cooled condition were measured via laser depletion 
to be (1.32 ± 0.10) x 10-17 cm2 molecule-1 at 308 nm and (9.6 ± 0.8) x 10-18 cm2 molecule-1 at 352 nm. The peak UV cross section 
is estimated to be (1.75 ± 0.14) x 10-17 cm2 molecule-1 at 330 nm.
