Identify all peaks in the NMR spectrum, identify and estimate the size of all coupling constants. The middle spectrum B is of a mixture of the two homo-dimers and the hetero-dimer. The 13C NMR spectra show the P-Ph signals only (not the Se-Ph ones). The spectra were taken on a 360 MHz NMR spectrometer (Reich, H. J.; Dykstra, R. R. Organometallics 1994, 13, 4578).

Error in the Table within the spectrum: It is ⁷⁷Se.

Ignore the spectrum (whitened) under Se in C
