Abstract

We present the first survey of the 3.4μm hydrocarbon absorption feature in active and IRAS galaxies. Comparison of our data with galactic studies of this feature provides insight into the nature of dust grains around active nuclei, and holds the potential to improve our understanding of interstellar dust.
