Environmental effects in galaxies. The data{

We present optical and millimetric data for 47 intermediate Hubble type spiral galaxies located either in dense environments or in the field. We compare correlations between global parameters, such as far-infrared luminosity, blue luminosity, and total molecular gas content, with other samples of galaxies, including normal galaxies, clusters and ultraluminous infrared galaxies. We find that overall our sample is a well-defined subset of these other samples of galaxies. Based on observations at the European Southern Observatory at the 15 m Swedish ESO Submillimetre telescope, SEST, and at the the 1.52 m telescope which is operated under the ESO-ON agreement.
