Comments: The UV spectra of NPTO2 and t-C4H9O2 have been determined relative to that of CH3O2; both are similar in shape and magnitude 
to those of other alkylperoxy radicals, displaying maxima around 240 nm, with sigma 240 nm(NPTO2)/ cm2 molecule-1 = (6.2 ± 1.1) x 10-18 and 
sigma 240 nm(t-C4H9O2)/cm2 molecule-1 = (4.7 ± 0.8)x 10-18.
Cross section data scaled by factor 4.58/4.80
