Scientific paper

Spectropolarimetric observations of the quasar 3C 273 over the range 3200-8000 A show wavelength-dependent polarization in the continuum, while the lines had no detectable polarization. The total polarization at the red end spectrum was near 2.5 percent, the highest ever measured for 3C 273. No wavelength dependence of the polarized flux is observed in most of the spectrum, while the position angle remains close to 130 deg. All these characteristics support a multiple synchrotron source model.
