摘要：

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 have 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 observational results in form of tables with line parameters or upper limits and spectra of detected sources. The anal sis of these data will be published separately.
