Two fields near the Galactic Center, containing the Quintuplet and Object #17 star-clusters, have been imaged with the ISOCAM circular variable filters (CVFs) in the wavelength range of 2.47 - 3.08 mu m and 3.99 - 9.09 mu m. Emission of [Ar II] 6.99 mu m is detected in the ''pistol-shaped'' H II region (G0.15-0.05) to the south bf the Quintuplet cluster. Absorption probably due to O-H stretching vibration (2.8 mu m) is evident in the Quintuplet spectra. In addition, Quintuplet members and the central part of Object #17 have CO2(4.3 mu m) and CO (4.7 mu m) absorption. Abundant CO2 might be present in these lines of sight.
