Abstract This paper gives an elementary introduction to time differential perturbed angular correlation of γ-rays emitted from excited nuclei with particular reference to nuclear quadrupole interactions. We start with a comparison to other techniques such as nuclear quadrupole resonance and the Mössbauer effect, quote all necessary formulae, describe a typical spectrometer, list suitable isotopes, and finally give some examples for modern applications.

The nuclear quadrupole interaction of 199mHg monitored by time differential perturbed angular correlations of γ-rays was employed to investigate the binding of Hg(II) to the binuclear metal site in the copper protein hemocyanin Eurypelma californicum. The data indicate that Hg(II) occupies the two metal sites and alters the metal site geometry from a trigonal to a digonal coordination
