Mapping and spectroscopy of the 3.3 microns feature in OrionThe results of spectroscopy of the 3.3 microns feature, H2 emission, and Br alpha, obtained in a spatial cut across the Orion ionization front are presented. The spatial distribution of the 3.3 microns feature peaks between the ionization front and the H2 peak are observed. The shape of the 3.3 microns feature observed at high spectral resolution shows no changes in regions of varying ultraviolet flux and density. The results are discussed in terms of current models for the 3.3 microns emission feature.
