摘要：

The first double quantum two-dimensional Fourier transform electron spin resonance (2D-FT ESR) experiments are reported. Extension of 2D-FT ESR to enable detection of the Delta M(s) = +/-2 transition enhances the capability of ESR in studying structural properties (i.e. distances in bilabeled molecules). A distance of 21 Angstrom was found for a poly-proline peptide, spin labeled at both ends, in agreement with earlier measurements using fluorescence energy transfer.
