  This paper presents the results of spectral observations for the largest
complete sample of very luminous IRAS galaxies obtained to date. The sample
consists of those 73 objects for which log (L_IR/L_sun) => 11.5 (H0=50
km/s/Mpc, q0=0.5) and mag =< 15.5, and was extracted from the 2 Jy IRAS
redshift catalog.
  All the spectra were obtained using 2.16m telescope of Beijing Astronomical
Observatory during the years 1994-1996. A total of 123 galaxy spectra were
obtained with spectral ranges of 4400A to 7100A and 3500A to 8100A at
resolutions of 11.2A and 9.3A respectively. In addition to the 73 spectra for
sample galaxies, we also present spectra for ten non-sample galaxies and a
further 40 for the companions of sample galaxies. The data presented include
nuclear spectrum and the parameters describing the emission lines, absorption
lines and continua as well as DSS images and environmental parameters.
