Abstract
Observations of 5 stellar sources with unusual characteristics of IRAS Low Resolution Spectra were made with the SWS on ISO. Observed stars are 4 late-type stars with silicate bands and one planetary nebula. Their IRAS LRS contain somewhat unusual features in respect of the 10/18 µm intensity ratio or narrow emission feature from unknown molecular bands. Some narrow unusual features are confirmed by ISO SWS01 spectra but the broad features were turned out to be false.
