ABSTRACT:The spectrum of infrared emission from interstellar dust grains is becoming known as a result of the recent successful mission of the Infrared
Astronomy Satellite (IRAS) and the continuing ground-based and balloon-borne
observations.
The present paper has the objective to compute in detail the infrared
emission expected from a graphite-silicate grain model, including the effects
of temperature fluctuations, and to compare 'predicted' emission
spectra with available observations.
Details regarding the considered
model are discussed, taking into account the radiation field, the grain
models, the physical properties of the grains, and the method of
calculation.
Attention is given to temperature distributions and predicted emission, the IR
emission from diffuse H I clouds, and the IR emission from dark clouds.
