An ESR line width study of vanadyl acetylacetonate (abbreviated as VO(acac),) in toluene has been carried out as a function of temperature at 9.5 GHz. It was found that VO(acac), was undergoing anisotropic reorientation with N-2.8 in 1 along a symmetry axis I' = l', where N is the ratio ofR,/R, and

โฆ Synopsis
ESR spectra of the iminosyl radical with the isotope 'jN have been calculated for molecular reorientation.
Two reorientation models were discussed: the rotational diffusion and rotational jump models. The spectrum shape was found to depend considerably on the rotational mode!.
