  The Infrared Space Observatory Long wavelength Spectrometerhas been used to
map distribution of the emission from a sample of 22 atomic, molecular and
ionised lines toward the Circumnuclear Disk at the Galactic Centre. The CND
disc is clearly seen in the maps of molecular lines such as CO and OH, whilst
the central region dominates in other atomic and ionised lines. The spectrum
toward Sgr A star is best represented by the sum of a 58 K blackbody,
superposed with 22 identifiable emission or absorption features, including four
lines each attributed to CO and OH, two broad features that may be indicative
of a complex of solid state features, two H2O lines, and the rest being various
atomic or ionised atomic lines.
