The first edition, by PR Bunker, published in 1979, remains the sole textbook that explains
the use of the molecular symmetry group in understanding high resolution molecular …

On closer examination, some of the spectroscopic assignments for the fourth excited 1∑+ g
state of H2 (4 d σ, P) and all of the ones for the fifth state (4 s, O) prove to be wrong. To aid …

The multichannel quantum defect theory (MQDT) method and large scale wave functions are
applied to the calculation of the cross sections and rates for dissociative recombination of …

▪ Abstract The vibrationally autoionizing Rydberg states of small polyatomic molecules
provide a fascinating laboratory in which to study fundamental nonadiabatic processes. In …

The cross section for H+ 2 dissociative recombination with slow electrons is calculated using
the multichannel quantum defect theory, with the set of molecular data used for the recent …

Publisher Summary This chapter presents an account of research into fundamental
questions, spanning roughly the past decade, and provides continuity from earlier reviews of …

Rotational effects on the dissociative recombination (DR) of the system H 2++ e are
investigated using multichannel quantum defect theory (MQDT). An explicit MQDT formula is …

Multichannel quantum-defect theory is applied to the highly accurate Σ g+ 1 ab initio excited-
state potential-energy curves calculated by Wolniewicz and Dressler [J. Chem. Phys. 82 …

The Born–Oppenheimer potential curves of the first two excited 1Σ+ g states of H2, EF and
GK, exhibit double minima which arise from avoided crossings between the electronic …

The observation of a new class of long-lived outer well states of ungerade symmetry (B′′
BΣ u+ 1) in molecular hydrogen, lying above the ionization threshold, is reported …
