WebThe 7 Li NMR study (− 80 °C) of crystals of 99 dissolved in THF shows a sharp resonance of the sandwiched Li + ions at δ = − 11.7 ppm and a broad resonance of extraneous cations … WebNov 1, 2008 · We apply here the dicluster model to the evaluation of static properties of 7Li and 7Be (e.g.magnetic dipole moment) as well as electromagnetic response to the continuum (in particular E1, E2 and M1). We use Energy Weighted Molecular Sum Rules (EWMSR) to check our calculations and we derive a new expression for the M1 EWMSR.
