摘要:
Electron paramagnetic resonance (EPR) and electron nuclear double resonance (ENDOR) spectra of (NH3+)-N-14 and (NH3+)-N-15, generated by X-ray irradiation of NH3 in argon and neon matrices, and of CH3 and (CH3)-C-13, generated in an argon matrix from CH3I during codeposition with Cs atoms, have been recorded. Analysis of the ENDOR spectra shows that the EPR spectra are inhomogeneously broadened due to a distribution of coupling constants for the central atom.
