Measured and calculated rotationally resolved photoelectron spectra for photoionization of low rotational levels of the (C) over tilde B-1(1) Rydberg state of water are reported. This is the first example of rotationally resolved photoionization spectra beyond the special cases of H-2, high-J levels, and threshold spectra. These spectra reveal very nonatomiclike behavior and, surprisingly, the influence of multiple Cooper minima in the photoelectron matrix elements.
