Abstract
We have analyzed a sample of more than 10 isolated interstellar clouds, which have been observed by IRAS in all four bands (12, 25, 60 and 100 µm). The clouds range from very diffuse with no measurable extinction to dense objects with more than 4m of blue extinction. The analysis of the distribution of energy emitted by each cloud over the four IRAS bands provides several results from which information on the general properties of grains in the infrared can be derived (Figure 1):
