HI and Molecular Line Observations of the 2 Jy IRAS-NVSS Sample at L-Band

We propose using the Arecibo telescope to study 85 infrared galaxies from the 2 Jy IRAS-NVSS sample. The observations will be carried out simultaneously for eight bands, namely the HI 21 cm and four 16 OH 18 cm lines in emission/absorption, HCN, HCO+, and the 18 OH isotope, using the full capabilities of the WAPP spectrometer. Our observations will yield better sensitivity and frequency coverage than any previous survey, and provide a complete, homogeneous set of high-sensitivity data for over half the Arecibo-accessible ob jects in the 2 Jy IRAS-NVSS sample. Among the scientific goals are to: 1) investigate the differences in physical characteristics (velocity width, HI mass, etc.) for sources with AGN's and those with pure starbursts; 2) study the OH gas properties, especially the occurrence of masers and activity in the OH satellite lines; 3) test the consistency of these galaxies with the Tully-Fisher relationship.
