Temperature	room temperature
Spectral Interval	15000-30000 cm-1 (666-333 nm)
Resolution	2 cm-1
further information	C. Hermans of the BISA group
Pressures O4 absorption cross-sections Wave number range: 15000-29800 cm-1 Resolution: spectra recorded at a resolution of 2 cm-1, but filtered afterwards ; (Cutoff freq. of the filter: 0.015 /Nyq.) Wave number units:cm-1 (in air) Cross-sections units:cm-5/molec-2 Room temperature These cross-sections are obtained from spectra recorded at different pressures (300-700 torr).
