Gas phase stabilities of cluster ions H +(CO) 2(CO) n, H +(N 2) 2(N 2) n and H +(O 2) 2(O 2) n with n=1–14

Abstract

Thermochemical stabilities of H + (CO) 2(CO) n , H + (N 2) 2(N 2) n and H + (O 2) 2(O 2) n with n electron-beam high-pressure mass spectrometer. The H + (CO) 2(CO) n cluster with n=4 has been found to form a rather solid first shell indicating the participation of covalent bond in the shell. For the H + (N 2) 2(N 2) n clusters the shell formation with and 7 is suggested. The H + (O 2) 2(O 2) n cluster with n=1 has been found to be much more stable than those with n⩾2. The ion may be represented as H +(O 2) 3(O 2) 2(O 2) n . The ring structure for the core ion H +(H 2) 3 has been proposed.
