The authors report {sup 13}C, {sup 87}Rb, {sup 39}K, and {sup 133}Cs nuclear magnetic resonance (NMR) measurements of lineshapes, Knight shifts, and spin-lattice relaxation rates in the normal and superconducting states of M{sub 3}C{sub 60}, where M{sub 3} = Rb{sub 3}, K{sub 3}, Rb{sub 2}K, RbK{sub 2}, Rb{sub 2}Cs, and RbCs{sub 2}. Measurements are used as a guide to a new ammonia solvent synthesis technique. Temperature dependence of the superconducting state electron spin susceptibility is found to follow BCS weak coupling predictions. The issue of the Hebel-Slichter coherence peak is addressed.
