Europium NMR

I had a post-doc come to me who _very_ much wants to do Europium
(solid-state) NMR. A quick look at the specs looked encouraging:

Al-27 Eu-151
spin 5/2 5/2
freq.(300) 78 74
abund. 100 48

Since Al-27 is so easy to see, I threw in an Eu nitrate solution.
Nothing. Lots of nothing. Reasonable sweepwidths, wide sweepwidths, very
wide sweepwidths. No "peaks" that weren't present with no sample as well.

A closer look as specs found:

elec. quad. moment: AL-27 0.149 Eu-151 1.16

A brief tour of the literature found very few papers on Europium NMR, and
they were at lHe temps and low or zero field.

Does anyone know of any literature on observing europium? Thoughts on
the possibility of even _observing_ a species with this large a quad.
moment?

Thanks,

Karen Ann
