The absorption and fluorescence excitation spectra of SO3 were measured in the 145-160-nm region with synchrotron radiation as a light source. The fluorescence spectra produced by excitation of SO3 at 147 and 157 nm were dispersed and compared with the laser-induced fluorescence spectrum of SO2, from which the emitter is identified to be the excited SO2*. The photodissociation process of SO3 is discussed in accord with the fluorescence observed.
