T. Pietrass et Pk. Burkert, N-23 AND C-13 SOLID-STATE NMR-SPECTROSCOPY OF TETRAMETHYLETHYLENEDIAMINE-SODIUMCYCLOPENTADIENIDE, Inorganica Chimica Acta, 207(2), 1993, pp. 253-254
The static Na-23 NMR spectrum of tetramethylethylenediamine-sodiumcycl
opentadienide revealed a lineshape that could not be unambiguously dis
cussed. Nutation NMR spectroscopy combined with MAS allowed a definite
assignment of the splitted signal to a second order quadrupolar inter
action with vanishing asymmetry parameter. The quadrupole coupling con
stant is in the range of 2 MHz. The C-13 CP-MAS spectrum yielded the e
xpected signals.
