The heats of formation for CHsCO and CFsCO molecules have been determined using ab initio molecular orbital calculations from isodesmic schemes. The heat of formation for CHJCO has been calculated as -4.2 +2 kcal mol-', which is in good agreement with experiment and that for CF,CO as -139.9 f 2 kcal
The equilibrium for proton transfer involving acetone and ketene (CH$OCHsH++ CH2CO -CH$O++ CHsCOCH3) has been studied in a pulsed ion cyclotron resonance spectrometer. Vtiues of 193.6 r I and 194.1 c 1 kcal/mole (1 kcal/mole = 4.18 kjoules) are obtained for the proton affinities of acetone and keten
The difference (AAf W ) between heats of formation of many multi-substituted odd-and even-electron positive ions can be described by a linear equation: Ah, ff = A + Bm, where rn is the number of substituents or ligands, relative to the unsubstituted reference ion, and m = 1, 2 or 3; A and B are the
