Our main knowledge about astrophysical environments relies on radiative spectra.
Absorption studies require background sources that are located hapharzadly in …

In the interstellar medium-the space between the stars in galaxies-new stars are born from
material that is replenished by the debris ejected by stars when they die. This book is a …

We have computed the intensities of some infrared and wavelength emission lines expected
from the photodissociated/photoionized envelopes of dark interstellar clouds. New atomic …

The role played by molecular radiative processes after the decoupling of matter and
radiation is discussed. In the physical environment of the expanding universe, molecules …

We report full-dimensional accurate quantum dynamical calculations of the rotationally
inelastic collision: para-H2 (1 0, j1 0) para-H2 (2 0, j2 0)→ para-H2 (1 0, j1) para-H2 (2 0, j2) …

The results of recent quantum mechanical calculations of cross-sections for rotational
transitions within the vibrational ground state of HD are used to evaluate the rate of radiative …

We present the results of quantal calculations of cross sections and rate coefficients for
rovibrational transitions in ortho-and para-, induced by collisions with ground state para …

The H2+ H2 system has long been considered a benchmark system for ro-vibrational energy
transfer in bimolecular collisions. However, most studies thus far have focused on collisions …

The excitation by X-rays and cosmic rays of molecular hydrogen in interstellar clouds is
analyzed. We carried out detailed calculations of entry efficiencies in rovibrational levels of …

We undertake calculations of the time-dependent structure of shock waves propagating in
dark and diffuse interstellar clouds. The results of the time-dependent model are compared …
