The far-infrared (FIR) emissivity of dust is an important parameter characterizing the physical properties of the grains. With the availability of stellar data bases and FIR data from Infrared Space Observatory (ISO), it is possible to compare the optical and infrared properties of dust, and derive the FIR emissivity with respect to the optical extinction. In this paper, we present the results of a systematic analysis of the FIR emissivity of interstellar clouds observed with ISOPHOT (the photometer onboard ISO) at least at two infrared wavelengths, one close to ~100mum and the other at 200 mum. We constructed FIR emission maps, determined dust temperatures, created extinction maps using Two-Micron All-Sky Survey data and calculated FIR emi...
