Abstract
Abstract
A molecular cloud is a type of interstellar cloud characterized by a high density (~ 104 cm-3) and variable temperatures that range between 10 and 300 K. In molecular clouds, the photoionization, and photodissociation processes caused by UV radiation are inefficient. In this type of clouds, chemical processes play an important role in star formation, with gas phase processes and interactions between ice grains and gas occurring. The Taurus Molecular Cloud 1 (TMC-1) is a type of dark cloud and is the closest star-forming region to the Solar System. Numerous molecules have been detected in TMC-1 with atoms of C, N, O and S, with carbon chains and cyanopolynes being of great importance. Therefore, understanding the physical and chemical conditions in TMC-1 would help piece together the chemical puzzle about the formation of large molecules in the interstellar medium
