Creasey, D.E. Heard, J.D. Lee Title: Absorption cross-section measurements of water vapour and oxygen at 185 nm. Implications for the calibration of field instruments to measure OH, HO2 and RO2 radicals Journal/Source: Geophys. Res. Lett., 27(11), 1651-1654, (2000); doi:10.1029/1999GL011014. Data: Energy/Wavelength range: 185 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: Absorption cross sections for oxygen and water vapour were measured using a low-pressure mercury lamp optically filtered to isolate the emission close to 184.9 nm.
