“…The last contribution till now to the diatomic ion-atomic gas problem was given by Viehland and coworkers in 2013 (Gharibi et al 2013), in a study of CO + in He. A new potential surface was calculated, and an approximate theory, treating the anisotropic scattering as an ensemble of scatterings on isotropic potentials, with some adjustable parameter, was used to estimate the mobility.…”

The two decades between 1960 to 1980 saw quite a fantastic development in diverse areas in physics, and so also in the quantitative theoretical treatment and deeper understanding of the behaviour of isolated electrons and ions in gases-that is 'charged particle swarm physics'. The evolution in swarm theory was strongly correlated with the contemporary advances in computer technology and the emergence of new and accurate experimental methods for finding charged particle transport parameters, as drift velocities, diffusion coefficients and reaction rates, and also with developments in neighbouring fields as plasma physics and the physics of electronic and molecular collisions. In 1960, low energy electron behaviour could already be calculated with reasonable accuracy in the so-called two-term approximation, while ion behaviour could only be treated at weak electric fields. By 1980, reasonably complete theories had been developed for perhaps most cases in interest-which is reflected in a number of reviews, books and journal articles published in the early 1980s. We will present a journey through the developments in this period and the basic theories behind the Boltzmann equation and Maxwell's transfer equations. We will also indicate how the interaction between different studies of the same basic processes have led to the elimination of shortcomings and a better understanding.

“…Similar calculations over wide ranges of T and E=N were not possible until the development of a method known as beyond-Monchick-Mason [23]. That method was used to compute the transport properties for CO + in He [12] and Na + in H 2 [21], but extending it to systems with four or more atoms seems unlikely in the near future.…”

Minimizing false positives in ion mobility spectrometry by changing the field or pressure

A method is proposed for minimizing false positives in ion mobility spectrometry by changing the value of E=N , the ratio of the electrostatic field strength to the gas number density. The feasibility of this method is demonstrated by simulation of the mobilities of 2,4,6-trinitrotolune and 2-methyl-3,5-dinitrophenol in helium. The zero-field mobilities of these ions are nearly the same, while their dependences upon E/N are so different that the ions can be distinguished by modest changes in E/N at 473 K and by somewhat larger changes at 300 K.
