✦ Synopsis

The rotational cutoff levels of C,( B' 'Z:, u" = 1,2), produced in the multiphoton dissociation of jet-cooled acetylene at 193 nm, have been measured using laser-induced fluorescence. This data is used to calculate the values AHf,,(C2) = 194.8iO.5 kcal/ mol and D,(CC-H) = 112.0 kO.8 kcal/mol, in excellent agreement with the latest theoretical calculations.

The C-H bond energy in C2H 6 is computed to be 99.76 \_+ 0.45 kcal/mol, which is in excellent agreement with the most recent experimental values. The calculation of the C-H bond energy by direct dissociation and by an isodesmic reaction is discussed.

The successive C-H bond dissociation energies of CH,, &Hz. C2H4, and H&O (ketene) are determined using large basis sets and a high level of correlation treatment. For CHI, C2H2, and C2H4 the computed values are in excellent agreement with experiment. Using our results we recommend 107.9 +2.0 and 96.

The acidities of the two different sites in naphthalene (1alpha and 1beta) and the electron affinities of the alpha- and beta-naphthyl radicals were measured using a Fourier transform mass spectrometer. Both carbon-hydrogen bond dissociation energies for naphthalene also were obtained, in this case

We present a theoretical study of the convergence of the C-H bond dissociation energy (Do) of acetylene with respect to both the one-and n-particle spaces. Our best estimate for Do of 130.1 f 1.0 kcal/mol is slightly below previous theoretical estimates, but substantially above the value determined
