We report the detailed non-Fermi-liquid (NFL) line shape of the dispersing excitation which defines the Fermi surface for quasi-one-dimensional Li{sub 0.9}Mo {sub 6}O{sub 17} . The properties of Li{sub 0.9}Mo {sub 6}O{sub 17} strongly suggest that the NFL behavior has a purely electronic origin. In relation to the theoretical Luttinger liquid line shape, we identify significant similarities, but also important differences. {copyright} {ital 1999} {ital The American Physical Society}
