Radiative Transfer

Radiative Transfer

This involves the absorption, emission, and scattering of radiation by molecules in space, affecting the population of energy levels and influencing the chemistry.

Maser Emission

Certain molecules, like OH, H₂O, and SiO, can emit microwave radiation coherently, leading to maser action. This can enhance specific transitions and be used to probe the physical conditions of the regions where these masers form.
