The chemical ionization reaction of the atomic oxygen radical cation with ethylene have been investigated extensively at 300 K in 0.5 Torr of helium in a selected ion flow tube (SIFT). To help understand the ethylene data, five additional terminal al

Metastable dissociations have been studied for trimethylsilyldimethylsilylenium ion, (CH 3 ) 3 Si–Si + (CH 3 ) 2 , and four bridged analogs, (CH 3 ) 3 Si–X–Si + (CH 3 ) 2 (X = CH 2 , O, NH, CC). Several dissociation pathways are observed, wi

The slow unimolecular dissociations (k ≈ 105 s-1) of gas-phase silylenium ions, SiCnH2n+3+ ions (n = 2−4) have been studied by mass-analyzed ion kinetic energy spectroscopy. On the microsecond time...

The relative kinetic energy distributions for the products of the dissociation of four metastable gas-phase ion clusters have been analyzed by means of ion kinetic energy spectroscopy, and the results modeled using statistical phase space theory. The

The photodissociation dynamics of the positive cluster ion of N 2 O and H 2 O have been examined for the wavelength range 657–458 nm (1.89–2.71 eV). The major products at all wavelengths are N 2 O + H 2 O, which are formed by excitation to a repu
