The complete millimeter-wave spectrum between 70 and 115 GHz of the giant Sgr B2 molecular cloud and the star-forming KL region of Orion has been surveyed with the NRAO 11 m telescope at a resolution of 1 MHz. The data are are presented. The NRAO survey of Sgr B2 complements that of Cummins, being more complete between 70 and 115 GHz and somewhat more sensitive. The NRAO survey of Orion-KL parallels that of the Onsala Space Observatory between 72 and 91 GHz, and is the first such survey of the 70-72 and 91-115 GHz regions. It is considerably more sensitive than the Onsala survey. In particular, many more unidentified lines are seen in the NRAO survey than in the previous ones, despite more recent spectroscopic data to aid in identifications. 8 refs.
