A brief review is given of the role of molecular positive ions in interstellar chemistry. It is indicated how the simplest ions, which are formed by photoionization and cosmic-ray ionization, are converted to polyatomic ions by sequential gas-phase ionic reaction processes such as proton transfer, carbon insertion and radiative association. The importance of H3 and CH3 ions in the initial stages of molecular synthesis and the analogous roles of H2D+ and CH2D+ (which are formed in the reactions…

Quantum chemical study of a new reaction pathway for the adenine formation in the interstellar space

Gas phase chemistry in the cold interstellar clouds is dominated by ion-molecule and radical-radical interactions, though some neutralneutral reactions are also barrier-free and efficient at cold

A selected-ion flow tube study of some gas-phase ion-molecule reactions of potential relevance to the chemistry of dense interstellar clouds

Results are reported for the studies of several systems of ion-molecule reactions of potential relevance to the chemistry of interstellar clouds. Measurements were obtained using a selected-ion flow

Destruction Rate of H3+ by Low-Energy Electrons Measured in a Storage-Ring Experiment

The cross section for dissociative recombination of vibrationally cold H3+ has been measured with an ion storage ring down to collision energies below 1 millielectron volt and a rate coefficient of 1.15 x 10-7 cubic centimeters per second at 300 kelvin was deduced.

Characterisation of the first electronically excited state of protonated acetylene C2H3 + by coincident imaging photoelectron spectroscopy

ABSTRACT We present a combined experimental and theoretical study of the threshold photoelectron spectroscopy of the vinyl radical encompassing the first triplet excited state of the vinyl cation.

Recent Sift Studies of Ion-Molecule Reactions: The Deuteration of Interstellar Molecules

About eighty molecular species have been detected in interstellar clouds to date (Irvine et al., 1988). Some of the observed molecules contain rare (heavy) isotopes, notably deuterium (Millar et al.,

Ab-initio method for X-ray absorption spectra simulation of hydride molecular ions

Soft X-ray absorption spectra of molecular ions are important data for the modeling and understanding of laboratory and astrophysical plasma. In this work, we present an ab-initio method, based on

Ab initio ro-vibronic spectroscopy of the Π2 PCS radical and Σ+1PCS- anion.

The present study provides theoretical predictions of the radical and its anion of the PCS radical for the first time and presents rotational and vibrational spectroscopic parameters to help aid in the identification and assignment of these spectra.

Structure and Vibrational Analysis of Protonated Ethane C2H7

The stability and vibrational frequencies of protonated ethane, C2H7+, have been studied by ab initio molecular orbital theory. The IR spectra for C2H7+ recorded by Y. T. Lee’s group were interpreted
