Application to Chemistry of Electric Quadrupole Perturbation of γ-γ Angular Correlations

Abstract

Perturbed angular correlations / Applications to chemistry AbstractThe fundamentals of perturbed angular correlations and the associated techniques arc presented, together with a review of recent applications to chemistry and hot atom chemistry.

Cadmium Uptake and Metabolism in Cultured Cells

“…Bakka et al (12) also used another method to study the binding modes of Cd in cells, namely, the spectroscopic technique of perturbed angular correlation of yrays (PAC). As far as we know, this is the first time PAC has been used for this purpose (13) (4). Also the study on the effect and toxicity of chelating agents led to the assumption that Cd exists in at least two pools within the cells.…”

Comprehensive study on the origin of orthorhombic phase stabilization in Gd-doped HfO2 and DFT calculations

“…The time-differential perturbed angular correlation (TDPAC) is a useful and efficient nuclear technique for the study of materials and has applications in chemistry, biology and condensed matter. 20 In the TDPAC (also called PAC) technique, 21–23 a radioactive probe nucleus ( viz. , 181 Hf/ 181 Ta, 111 In/ 111 Cd and several others) is introduced into the materials under investigation.…”

“…The time-differential perturbed angular correlation (TDPAC) is a useful and efficient nuclear technique for the study of materials and has applications in chemistry, biology and condensed matter. 20 In the TDPAC (also called PAC) technique, [21][22][23] a radioactive probe nucleus (viz., 181 Hf/ 181 Ta, 111 In/ 111 Cd and several others) is introduced into the materials under investigation. The local environment of the probe in the material can be studied through the hyperfine interactions of the electric quadrupole/magnetic dipole moment of the probe nucleus and the electric field gradient/magnetic field generated at the probe nuclear site by the surrounding charge distribution.…”

Perturbed angular correlation spectroscopy and its application to metal sites in proteins: possibilities and limitations

“…A detailed account of PAC theory can be found in Frauenfelder & Steffen (1966). More recent accounts with special emphasis on chemical application are also available (Adloff, 1978;Rinneberg, 1979;Haas & Shirley, 1973).…”
