Scientific paper

Absorption lines of CO(1-2), CO(2-3), HCO+(1-2) and HCN(1-2) have been detected at a redshift of Z(a) = 0.68466 towards the background BL Lac object B0218+357. The CO and HCN lines are strongly saturated, while the HCO+ line is mildly saturated. Lower limits to the column densities are given. The filling factor for the background source is larger than 0.7-0.8. The absorption line profile is asymmetric with a width of approximately 30 km/s B0218+357 is a gravitational lens candidate with two compact continuum sources separated by 335 mas (1.8 kpc). The small linewidth of the molecular absorption puts constraints on the inclination and position angle of the lensing galaxy. We also report a search for quasi stellar objects (QSO's) molecular absorption lines in 12 other redshifted systems; none were detected.
