Sign and magnitude of the phosphorus-phosphorus coupling constant in the [cyclopentadienyltris(trimethylphosphine)iron]+ cation of [(η5-C5H5)(Me3P)3Fe]BF4and the 13C/12C isotope effect on the 31P chemical shift

Sign and magnitude of the phosphorus-phosphorus coupling constant in the [cyclopentadienyltris(trimethylphosphine)iron]+ cation of [(η5-C5H5)(Me3P)3Fe]BF4and the 13C/12C isotope effect on the 31P chemical shift

The 13C NMR methyl group multiplet of the [cyclopentadienyltris(trimethylphosphine)iron]+ cation was simulated to obtain the sign and magnitude of the phosphorus‐phosphorus coupling constant and the 13C/12C isotope effect on the 31P chemical shift.
