Emission and absorption spectra of several molecules have been used to trace the kinematic patterns of molecular material in the inner Galaxy. For a variety of reasons, the great majority of effort in this area has focussed on the region 357 ≳ ℓ ≳ 3° very near the plane b = 0°. Extending the observational coverage of the molecular distribution away from this plane and over a wider longitude range is a tedious process only now beginning and severely hampered by relatively small beamwidths and long integration times. Our knowledge of the arrangement of molecular material in the inner few kpc of the Galaxy is primitive and quite incomplete compared to that of the atomic gas sampled at λ21 cm.
