Cj. Feng et al., The first heteronuclear terbium-zinc cryptate - An electrospray mass spectrometric investigation, SPECT LETT, 32(6), 1999, pp. 1033-1039
Electrospray mass spectrometry (ESMS) is described for heteronuclear terbiu
m-zinc cryptate derived from tris(2-aminoethyl)amine (tren) and 2,6-diformy
l-4-t-Butyl-phenol. The mass spectral data were compared with those of corr
esponded mononuclear terbium cryptate to verify the co-existence of zinc in
the cryptate through isotope distribution calculation. This is the first h
eteronuclear cryptate studied by using ESMS.
