New equilibrium thermodynamic distribution models of organic substances important to life in giant molecular clouds are suggested. These models use the normal distribution law of the standard enthalpy and the free energy (Helmholtz energy) for various organic molecules, amino acids, and nucleic acid components. These models were used to forecast organic molecule resources in the interstellar medium of the observable universe. The resources of the main biological molecules were estimated from…

Systematic Search for Chemical Reactions in Gas Phase Contributing to Methanol Formation in Interstellar Space.

A massive search for chemical routes leading to methanol formation in gas phase has been conducted using computational chemistry, at the CBS-QB3 level of theory, to identify reactions with the necessary features to be viable in the interstellar medium (ISM).

Kinetic Monte Carlo method for simulating astrochemical kinetics: Test calculations of molecular hydrogen formation on interstellar dust particles

Molecular hydrogen formation on the surfaces of interstellar dust grains has been studied numerically. Different stochastic methods (analogue Monte Carlo methods, direct solutions of the chemical

Interstellar Molecular Clouds

The molecular phase consists of giant clouds, which are the largest gravitationally bound objects in the galaxy, the primary reservoir of material for the ongoing birth of new stars, and the medium regulating the evolution of galactic disks.
