Lithium in the gel: The NMR spectroscopic properties of common organolithium and lithium amide reagents are investigated in the anisotropic environment of a stretched polystyrene (PS) gel. PS is stable towards reactive organometallic compounds and can be used at low temperatures. The residual quadrupolar couplings (RQCs) from a single (7)Li NMR spectrum can distinguish between high (hexamer, tetramer) and low (dimer, monomer) aggregation states (see scheme).
