The photolysis of SOz at 3080 A, FWHM = I50 A, and 22ยฐC has been investigated in the presence of cis-and trans-CzFzH2. Quantum yield measurements for the photosensitized isomerization of cis-C2FZH2 to trans-CzFzH2 have been made for a variation in the [SO2]/[czs-C2F2H2] ratio from 0.992 to 253. The
The difference in energy between cis-and tram-1,2-difluoroethylene is accurately computed at the SCF level with near Hartree-Fock wavefunctions usmg either of two internally consistent sets of optimized geometries. The inaccuracy of calculations with smaller basis sets is attributed m part to an ove
