3C 318 is a z=1.574 radio-loud quasar. The small physical size of its radiojets indicate that these jets were triggered relatively recently. In additionto the ultraviolet continuum emission being reddened by dust, detections withIRAS and SCUBA show it to have an exceptionally high far-infrared luminosity.We present CO(2-1) observations of 3C 318 made with the IRAM Plateau de BureInterferometer. We detect CO(2-1) emission with a FWHM=200 km/s at asignal-to-noise ratio of 5.4. There is evidence for positional (~ 20 kpc) andvelocity (~ -400 km/s) offsets between the molecular gas and the quasar whichmay be due to the quasar experiencing a major merger. The mass of molecular gasinferred from our observations is M_{H_2}=(3.0 +/- 0.6) x 10^{10} M_sun. Thismolecular gas mass is comparable to that in sub-mm-selected galaxies at similarredshifts. The large molecular gas mass is consistent with the primary sourceof heating for the cool dust in this quasar to be massive star formation with astar formation rate of 1700 M_sun/yr and a gas depletion timescale of 20 Myr.Our observations support the idea that star formation episodes and jettriggering can be synchronised.Comment: 4 pages, 3 b/w figures, AJ, in pres
