✦ Synopsis

The quadrupole splitting E was measured between 90 and 350 K for the compounds Fe(NHj;hX2 and Fe(NDs)& where X = (11, BF4 and SiF6. At 100 K the tetrafluoroborate.shows a relative isotope effect {E(deuterated} -E(hydrogenated)}/c(hydrogenated) of about 10%. In the case of the tetiafluoroborate, too, the isotope effect ir. str?ngIy temperature dependent and represents 20% of the temperature vruiation of c(Fe(NH3)6(BFa)z).

For the ch!oride and hzsafluorosilicate the results are less impressive.

The thermal decomposition of graphite ferric chloride produces graphite ferrous chloride with two quadrupole splittings for iron. One of these is the same as the single splitting in bulk FeCl,. The other is larger and has an intensity, relative to the normal splitting, which increases with flake thi

The effect of annealing on the paramagnetic and ferromagnetic phases of tempered tool steel was studied by Mbssbauer spectroscopy as a function of the annealing parameter. The quantity of the paramagnetic materials first decreased due to the decompositioh of austenite. After the minimum, the percent
