The positions of conformational equiliirium in disubstituted arene chromium tricarbonyl complexes, i.e. alkylanisole chromium tricmbonyl complexes and alkylbenzoate chromium tricarbonyl complexes, have been determined by 'H N M R spectroscopy. It has been found that the donor effect is the dominant
## H and "C NMR spectra of benzophenone-Cr-(CO), and ji'uorenone-Cr(C0)3 have been recorded and fully assigned. Very large upjield coordination shifts of the resonances of the directly bonded rings are evident. A discussion on the nature of such shifts is made on the basis of the results of CNDO mlc
