摘要：

The1H-NMR spin lattice relaxation times of aetiobiliverdin-IV-γ and biliverdindimethylester were determined using the inversion recovery technique. The relaxation times of protons attached to the terminal rings A and D are longer than those situated at the rings B and C which points to a higher mobility of rings A and D. Moreover these measurements allowed an independent assignment of the1H-NMR-signals of the methyl groups of biliverdindimethylester. © 1979 Springer-Verlag.
