CO OBSERVATIONS OF SPIRAL GALAXIES IN THE VIRGO CLUSTER AND IN THE COMA A1367 SUPERCLUSTER/

We present new observations of the (CO)-C-12(1 - 0) Line in 34 spiral galaxies, 24 in the Virgo cluster, 9 in the Coma supercluster region a nd one in Abell 2197. The observations have been made at the SEST 15 m and the Onsala 20 m telescopes. 21 of the observed galaxies were dete cted. For galaxies in common with other surveys we have 3 new detectio ns, 2 improved upper limits and 4 confirmed detections. Since the gala xies have been observed at the central position only, the CO data are used to determine a lower limit to the H-2 content. The analysis of th ese data is presented in Boselli (1994).
