Abstract
We have used the 100-m Effelsberg and 32-m Medicina radiotelescopes to search for H2O maser emission (22.235 GHz) towards 1143 IRAS sources, for OH (1665/67 MHz) towards 303 IRAS sources, and for CH3OH (12.179 GHz) towards 19 IRAS sources. The IRAS sources have been selected to h ave colours of pre-main sequence objects. To obtain an estimate of the (kinematic) distance we observed (CO)-C-12(J = 2 --> 1) and (CO)-C-12 (J = 3 --> 2) with the KOSMA 3-m telescope towards 25 sources showing H2O emission and not yet observed in CO. This paper presents the obser vational results in form of tables with line parameters or upper limit s and spectra of detected sources. The anal sis of these data will be published separately.
