The study maps the 3.3-micron emission band and the continuum at 3.2 microns on a 9x4-arcmin area in the direction of the H II region-molecular cloud interface M17 southwest, with a 30-arcsec beam. The 3.4-micron feature was measured along a single east-west strip. It is shown that the 3.3-micron emission band intensity traces a ridge between the H II region and the molecular cloud, whereas the 3.2-micron continuum is emitted in the H II region and exhibits a spatial distribution which is similar to the 10-micron continuum. It is shown that the 3.3-micron emitting material is located in the direction of the molecular cloud and is practically absent from the H II region. A comparison with larger beam measurements shows that except for the H II region, the fraction of the total IR flux radiated in the 3.3-micron band is roughly constant throughout the complex and equal to 0.0006.
