Abstract -- The strengths of magnetic fields in interstellar gas clouds are obtained through observations of the circular polarization of spectral line radiation. ... To infer information about these irregularities from the observational data, we develop statistical relationships between the rms values of the irregular component of the magnetic field and spatial variations in the circular polarization of the spectral line radiation. ...
