摘要：

The spectra between 3.15 and 3.45-mu-m are presented for four IRAS sources; IRAS 05355 + 3039, 06294 + 0352, 06335 + 1057, and 06210 + 1432 which possess IRAS spectra similar to reflection nebulae. The prominent emission feature at 3.3-mu-m of the order of 10(-19) W cm-2 has been detected in the four sources, and the adjacent feature at 3.4-mu-m in two of them. The 3.3-mu-m band strength is used to derive the contribution of small dust to the overall energy spectrum, which is about 20% in the 1-100-mu-m infrared region.
