Measurements of upper limits on the continuum fluxes at 1.3, 3, and 7 mm, as well as centimeter-wavelength continuum and 3 mm CO line observations, are reported for a sample of 17 radio-quiet AGN selected from the IRAS Point Source Catalog. A variety of spectral shapes was found in a search for a low-frequency tail of the IR emission, including high-frequency excess at 2 cm in many sources. A search for far-IR emission from cool dust was negative except for the quasar I Zw 1. The CO luminosity of I Zw 1 is similar to the CO luminosities of IRAS galaxies with comparable far-IR luminosity. 41 refs.
