Scientific paper

It is shown that on theoretical grounds the relative abundances of the elements in the interstellar gas phase should be correlated with the wavelength of maximum interstellar polarization λmax. If these correlations can be determined by observations, then there is the possibility to determine the relative abundances of the heavier elements within the mantles as well as within the cores of interstellar dust grains, at least in principle. The observational data available up to now confirm the existence of such correlations between λmax and the interstellar gas phase abundances of titanium, iron, magnesium, and carbon.
