The sup 53}Cr NMR spectra of 46 chromium-carbene complexes were recorded, and chemicalshift and line width data are reported, along with associated infrared, uv-visible, and sup13}CNMR spectroscopic data. The sup 53}Cr chemicalshifts correlated very well with the donor-acceptor properties of the carbene ligand and were quite sensitive to steric influences on efficiency of pi}-overlap of the
