Abstract:We describe a Herschel Space Observatory 194-671{mu}m spectroscopic survey of a sample of 121 local luminous infrared galaxies and report the fluxes of the CO J to J-1 rotational transitions for 4<=J<=13, the [NII] 205{mu}m line, the [CI] lines at 609 and 370{mu}m, as well as additional and usually fainter lines. The CO spectral line energy distributions (SLEDs) presented here are consistent with our earlier work, which was based on a smaller sample, that calls for two distinct molecular gas components in general: (i) a cold component, which emits CO lines primarily at J<~4 and likely represents the same gas phase traced by CO (1-0), and (ii) a warm component, which dominates over the mid-J regime (4<J<~10) and is intimately related to current star

In this paper we presented a Herschel SPIRE/FTS 194-671um
spectroscopic survey of 121 galaxies belonging to a complete,
flux-limited sample of 123 luminous infrared galaxies (LIRGs) down to
a total IR flux of 6.5x10^-13^W/m^2^, selected from the Great
Observatories All-Sky LIRG Survey (GOALS; Armus+ 2009PASP..121..559A).
All 123 observed targets are listed in Table 1.
