Scientific paper

The properties of a sample of color-selected quasars from the IRAS Point Source Catalog have been compared with those of a larger sample of PG quasars detected by the IRAS. Fe II emission is shown to be prominent in quasars with strong IR luminosity relative to optical luminosity. Two of the seven quasars observed by the IRAS have energy distributions which are similar to those of the typical PG quasars, while the others are much redder.
