Electrospray mass spectrometry of lanthanide β‐diketone complexes. II‐Ligand‐exchange processes involving acetate ions and Ln(tfc)3 complexes

Electrospray ionization on Ln(tfc)3 complexes (Ln = Eu, Yb; tfc = D‐3‐trifluoroacetylcamphorate) was performed with samples dissolved in methanol–water containing acetic acid. The spectra were obtained with a four‐sector mass spectrometer. The mass spectra exhibit ions containing tfc ligand in addition to ions with acetato ligand. Electro‐spray and tandem mass spectra are presented.
