electric field gradient

电场梯度

四极核总是处于自身及周围电荷所形成的电场中,若 电场梯度( EFG, Electric Field Gradient) 不为零,四极核将与电场发生相互作用,呈现出电四极矩,由于电四极矩的作用,使原子核具有相应的能量...

abstract: In atomic, molecular, and solid-state physics, the electric field gradient (EFG) measures the rate of change of the electric field at an atomic nucleus generated by the electronic charge distribution and the other nuclei. The EFG couples with the nuclear electric quadrupole moment of quadrupolar nuclei (those with spin quantum number greater than one-half) to generate an effect which can be measured using several spectroscopic methods, such as nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR, ESR), nuclear quadrupole resonance (NQR), Mössbauer spectroscopy or perturbed angular correlation (PAC).
