Gas phase Elemental abundances in Molecular CloudS (GEMS) is an IRAM 30 m Large
Program designed to provide estimates of the S, C, N, and O depletions and gas ionization …

Emission from high-dipole moment molecules such as HCN allows determination of the
density in molecular clouds, and is often considered to trace the" dense" gas available for …

Hydrogen cyanide (HCN) is considered a good tracer of the dense molecular gas that
serves as fuel for star formation. However, recent large-scale surveys of giant molecular …

HCN and HNC are two fundamental molecules in the dense interstellar medium. The
HNC/HCN abundance ratio depends on the kinetic temperature and can be used to explore …

New calculations for rotational excitation of cyanoacetylene by collisions with hydrogen
molecules are performed to include the lowest 38 rotational levels of HC3N and kinetic …

The potential energy surface (PES) describing the interaction of the methanol molecule with
molecular hydrogen has been calculated by the use of the explicitly correlated coupled …

Protonated molecules have been increasingly detected in the interstellar medium (ISM), and
usually astrochemical models fail at reproducing the abundances derived from …

Deuterium fractionation provides a window into the thermal history of volatiles in the solar
system and protoplanetary disks. While evidence of active molecular deuteration has been …
