The authors have used a magnetic bottle photoelectron spectrometer to study the distribution of ion rotational states following photoionization of selected rotational states of the {tilde C}(0,0,0) state of water by 355 nm light. The spectrometer`s kinetic energy resolution of about 4 meV was sufficient to yield rotationally resolved time-of-flight photoelectron spectra. Comparison of the measured and calculated photoelectron spectra is encouraging and reveals unusual photoionization dynamics due to very nonatomic-like behavior in the photoionization continuum and to the presence of Cooper minima. This is the first time that such a test of photoionization theory for a polyatomic molecule at finite kinetic energy has been possible.
