ESR Rigid-Lattice Line Shape in a System of Two Interacting Spins
Abstract
A theory is developed to describe the rigid-lattice line shape of an electron spin resonance signal which is influenced by dipolar coupling to a second spin. The polarization lifetime T1 of the dipolar field is assumed short. Computer generated plots are presented. Broadening, peak shifts, and amplitude changes are noted. Under certain conditions no observable broadening is predicted, merely an apparent decrease in spectrum amplitude. Experimental results for a nitroxide radical interacting with a paramagnetic ion are compared with theoretical curves. The results allow calculation of the distance between the two spins. Values for the directional angles of the second spin in the g tensor coordinate system of the observed spin are also calculated.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
