This paper describes a procedure for optimal rounding of parameters determined from a
linear or nonlinear least-squres fit in order to minimize the number of digits which must be …

H+ 3 potential energies and multipole moments are calculated from a full CI with a 10 s, 4 p,
2 d GTO hydrogen basis. 69 calculated energy points with energies of up to 25 000 cm− 1 …

The study of molecular ions was greatly accelerated by Oka's1 development of tunable
infrared laser absorption spectroscopy of glow discharges in 1980 via his initial detection of …

H+ 3 plays important roles in many fields (1), including interstellar chemistry, the study of
planetary ionosopheres, and theoretical calculation of rovibrational energy levels of …

The dissociative recombination rate coefficients for H+ 3, HN+ 2, and HCO+ are determined
at 110, 210, and 273 K by monitoring the decay of the infrared absorption signals as a …

This review discusses the H 3+ molecular ion and its deuterated isotopomers. The ion is
important because of its fundamental nature, astrophysical significance and dynamical …

Molecular structure is the most basic information about a substance, determining most of its
properties. Determination of accurate structures is hampered in that every method applies its …

The infrared spectrum of the degenerate ν3 vibration–rotation band of methyl cation CH+ 3,
one of the most fundamental carbo‐ions, has been observed and analyzed. The spectrum …

Adiabatic global potential energy surfaces, for singlet and triplet states of A′ and A
″symmetries, were computed for an extensive grid for a total of 8469 conformations of H 3+ …

New MiZo line lists are presented for the D2H+ and D isotopologues of H. These line lists
plus the existing H MiZATeP and the ST H2D+ line lists are updated using empirical energy …
