Semi-cmpiriwl SCF calculntions fCNDO/7-) of the trigonnl-bipyramidal molecule ClOzF3 proved the Czv cont$,uration to hnvc the highest strtbilizntion, in accord wiih empirical rules, and with an interpretation of the IR sFecrntm of :1 wry recent first preparation of th!; compound. 1. lritroduction Quantum chemical treatment of the mo!ecule CtOzF3 appeared of interest in view of the possible csistcnce of several configurations of thir trigonal-&pyramidal molecule. MO cakulations should lead to ~nfornlation about the relative! stabifity of the various configurations and facilitate general conclusions in regard to similar problems. An analogous compound of iodine, IO,F,, has Lzecn prcpszed recently [i] , but B detinite determina-

Calculations on some isocyanates h3~1! been performed by rnwn5 of semi-anpiric;ll hl0 methods (CNDO/Z). The NC0 group is found to be nonlinear, in agreement with recent esperimcntai results. Energies, charge densities and bond indices are dkcussd in relation to the stability of these compounds.
Non-empirical LCAO MO SCF studies on CH: indicate that the C, geometry is notab& iess stable than the Dgh or C+v configurations. CKDO/2 calculations using the original Pople parameters also indicate that the D3h and Cg,, configurations are more stable than the Cs geometry. In contrast to this the pa
