High signal-to-noise ratio 5-8 ..mu..m spectra of four sources embedded in molecular clouds are presented. All four sources show evidence for the presence of absorption features. The shape of these features changes, however, dramatically from source to source. They range from two relatively narrow bands at 6.0 and 6.8 ..mu..m in W33A to a broad, shallow feature, which extends from about 5.2 to 7.8 ..mu..m and shows some structure, in Mon R2-IRS2, BN, and NGC 2264.
