Scientific paper

We present HI 21-cm and OH 18-cm spectral line analysis of eighty-five luminous infrared galaxies from the 2 Jy IRAS-NVSS sample observed with the 305 m Arecibo Radio Telescope. We detected HI in 82 galaxies (16 new detections), and OH in 8 galaxies (4 new detections). In some cases, the HI spectra show the classic single-peak or double horn profile, while the majority exhibit distorted features indicating that the galaxies are in interacting/merging systems. The ULIRG IRAS 23327+2913 is discussed in greater detail since both HI emission and OH megamasing activity are new detections.
This ULIRG consists of two galaxies separated by 0.2 arcsec and it is thought to be an early-stage merger.
