CARMA $\lambda$ = 1 cm Spectral Line Survey of Orion-KL
  Orion-KL is a well known high mass star forming region that has long been the
target of spectral line surveys and searches for complex molecules. One
spectral window where the region had never been surveyed is around wavelengths
of $\lambda$=1 cm. This is an important window to observe due to the
fundamental and low energy transitions of numerous complex molecules that
indicate the maximum spatial extent of the molecular species; knowing the
spatial distribution of a molecule aids in determining the formation
mechanism(s) of that molecule. Additionally, there are fewer transitions in
this window, reducing confusion caused by blended lines that can be very
problematic at shorter wavelengths ($\lambda<$3 mm). In this work, we present
the first spectral line survey at $\lambda$=1 cm of the Orion-KL region. A
total of 89 transitions were detected from 14 molecular species and
isotopologues and two atomic species. The observations were conducted with the
Combined Array for Research in Millimeter-wave Astronomy in both
interferometric and single dish modes.
