  We have initiated a spectral line survey, at a wavelength of 3 millimeters,
toward the hot molecular core Sagittarius B2(N-LMH). This is the first spectral
line survey of the Sgr B2(N) region utilizing data from both an interferometer
(BIMA Array) and a single-element radio telescope (NRAO 12 meter). In this
survey, covering 3.6 GHz in bandwidth, we detected 218 lines (97 identified
molecular transitions, 1 recombination line, and 120 unidentified transitions).
This yields a spectral line density (lines per 100 MHz) of 6.06, which is much
larger than any previous 3 mm line survey. We also present maps from the BIMA
Array that indicate that most highly saturated species (3 or more H atoms) are
products of grain chemistry or warm gas phase chemistry. Due to the nature of
this survey we are able to probe each spectral line on multiple spatial scales,
yielding information that could not be obtained by either instrument alone.
