Pulsed ESR-based Electron Spin Transient Nutation (ESTN) spectroscopy has been extended to field-swept two-dimensional fine-structure ESR spectroscopy in non-oriented media. 2D ESTN spectroscopy inherent in the nature of pseudo zerofield time-domain spectroscopy intensifies resolution enhancement in terms of spin identification for high-spin mixed fine-structure spectra. The resolution enhancement intrinsic to 2D ESTN spectroscopy does not require cw fine-structure spectra of high quality. Some theoretical aspects of ESTN spectroscopy are discussed. Also, unequivocal and experimental identifications of molecular spin quantum numbers for fine structure spectra in non-oriented media are exemplified. © 2000 American Institute of Physics.
