✦ Synopsis

Combining the techniques of molecular beam and vacuum ultraviolet synchrotron radiation photoionization mass spectroscopy, we have measured the ionization energy of NH 3 (10.16 + 0.02 eV) and the appearance potentials of H + (18.57 +0.05 eV) and NH~-(15.75 +0.02 eV). From these data, we have obtained dissociation energy values for Do(H2N-H) (4.97 + 0.05 eV), D0(H2N+-H) (5.59 + 0.02 eV) and Do(H2N-H +) (8.41 + 0.05 eV) and the ionization energy IE(NH 2) (10.78 + 0.05 eV). High-level ab initio calculations lead to results that are in good agreement with the experimental findings.

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.

Charge transfer and hydrogen atom pickup cross sections are reported for N+-H20( D,O) collisions at center-of-mass energies between I and 25 eV. Time-of-flight measurements were performed to determine the charge transfer product ion kinetic energies. The exothermic charge transfer proceeds rapidly
