摘要
The temperature-dependent chemical shifts in NMR spectra of gases arise from a combination of the intrinsic temperature dependence of chemical shielding in an isolated molecule and the temperature dependence of the effects of intermolecular interactions. Both contributions have been measured for the 31P and 19F nuclei in NF3, PF3, POF3, and PF5. The intramolecular contribution can be interpreted in terms of the derivatives of nuclear shielding with respect to bond extension and angular displacement. © 1979 American Chemical Society.
