The torsional data for CF,NO have been reinvestigated. A model with a single degree of freedom and three adjustable parameters is sufficient to fit data to u = 8 in the electronic ground state. For CF3NO we obtain F,J = 1.9822(42) cm-', V3 = 238.4(1.6) cm-l and V6 = -5.8(1.6) cm-' or Fo = 1.9894(66)
The barrier to internal rotation for the 0" angle (using Olson and Flory's notation) in the ngar-phosphate-mgar complex, CloH IgOaP, has been obtained from ab initio computations. The barrier height at 0" = 60" is 4.5 kcalimole, a: 0" = 180" is 3.3 k&/mole and at 9" = 310" is 7.5 kcal/mole. The corr
