Core binding energies were determined for the following gas-phase molecules: CH/sub 2/CCH/sub 2/, CH/sub 2/CO, BH/sub 3/CO, HNCO, CH/sub 3/CN, CH/sub 3/NC, NH/sub 2/CN, t-BuNC, and C/sub 6/H/sub 5/NC. By use of the equivalent cores approximation, these data and data from the literature were used to calculate the proton affinities of N/sub 2/O, CO/sub 2/, HCCF, NCF, NH/sub 2/CN, CH/sub 2/N/sub 2/, HNCO, CH/sub 2/CO, HN/sub 3/, CH/sub 3/NC, and CH/sub 3/CN with an estimated accuracy of +/-7 kcal mol/sup -1/. By a similar method, the isocyanide-to-nitrile isomerization energies for CH/sub 3/NC, t-BuNC, and C/sub 6/H/sub 5/NC were calculated to be -30, -27 and -28 kcal mol/sup -1/, respectively.
