Abstract We make an ab initio calculation of the bending distribution functions for low lying vibrational states of the CO2 molecule in its ground electronic state. These functions have their maximum values at a non-linear geometry, and the value zero at linearity, despite the fact that the potential surface has its minimum value at linearity. These functions are in accord with experimental distribution functions inferred by analysis of Coulomb Explosion Imaging experiments. Thus in a femto… Expand

Abstract The relation r 0 > r e is a well established wisdom in molecular spectroscopy. However, when we compare r e with the r 0 , eff , derived from the experimentally determined rotationalExpand

Jensen (Can. J. Phys. 98, 506 (2020). doi: 10.1139/cjp-2019-0395 ) presents theoretical justification for the claim that linear triatomic molecules are necessarily observed to be bent. The basis ofExpand

In Amano’s comment on Jensen’s paper, we notice two important misconceptions: (i) Amano overlooks the fact that all features special for a linear molecule originate in the double degeneracy in theExpand
Excited state quantum phase transitions in the bending spectra of molecules
We present an extension of the Hamiltonian of the two dimensional limit of the vibron model encompassing all possible interactions up to four-body operators. We apply this Hamiltonian to the modelingExpand

Ro-vibrationally averaged dipole moments of linear triatomic molecules
Abstract We discuss here which of the dipole moment components of a linear triatomic molecule (of type A–B–A or A–B–C) will vanish, and which can be observed with non-zero values. We aim to resolveExpand
