TL;DR: In this paper, the authors presented state-to-state rate coefficients among the 45 lowest levels of o-H2O with H2(j2 = 0) and Δj2= 0, +2, as well as with H 2(j 2 = 2) and δj2 ≥ 0, − 2a ndj2 = 2 with Δj 2 ≥ 2.

TL;DR: Using a recoupling technique with close-coupling spin-free calculations de-excitation rate coefficients are obtained among hyperfine transitions for He colliding with N 2 H +, and a recently determined potential energy surface suitable for scattering calculations is used to investigate rate coefficients for temperatures between 5 and 50 K as mentioned in this paper.

TL;DR: In this article, a large velocity gradient and nonlocal radiative transfer calculations involving the rotational and hyperfine structure of the spectrum of N2H+ with collisional rate coefficients were presented.

TL;DR: In this article, a newly determined 5D potential energy surface for H2-H2O was used to provide an extended and revised set of rate coefficients for de-excitation of the lowest 10 para- and 10 ortho- rotational levels of H2O by collisions with para-(j=0) and orthoH2(j=1), for kinetic temperatures from 5 K to 20 K.

TL;DR: In this paper, the rotational transitions of N2H+ and N2D+ toward a sample of prototypical dark clouds have been interpreted using nonlocal radiative transfer models.
