✦ Synopsis

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 mlculations on benzene-#(C0)3.

molecule of the series. In this respect, the calculated parameters (charges and bond orders) have been fitted to the chemical shift semiempirical relationships of the literature.

The 'H and -C NMR spectra of a series of 1,3,2-dioxarsolanes have been obtained at 2.1T and some at 9.4T. The chemical shifts and spin-spii coupling constants have been obtained from complete spectral analyw of the 'H and proton-coupled -C spectra. The spectral data are interpreted on the basis of t
