In the investigation of rotating spectra concerning the interstellar medium, machine-learning approaches have been documented as effective instrument. The understanding of molecular rotational transitions in space and can be a significant source of information on the dynamics, physical properties, and chemical make-up of interstellar spaces. Traditional analytical techniques are however confronted with difficulties when dealing with the enormous and complicated information produced by telescopic observations. The handling of these massive datasets and the extraction of useful data from rotating spectra can be accomplished using machine learning methods, which are a promising approach. This article gives a general overview of the developments of machine learning in the analysis of rotational spectra in the interstellar medium. It goes over how to recognize and describe molecular transitions using supervised and unsupervised learning algorithms, deep learning architectures, and spectral line fitting methods. Also, machine learning algorithms can aid detection of spectral lines that are weak or infrequent but may contain important data regarding the chemical complexity of interstellar areas.

They help make new molecular discoveries and enable the research of previously undiscovered spectral regions in the electromagnetic spectrum. Despite these developments, there are still problems to be solved, such as handling data noise, uncertainty, and over fitting. By enabling effective and automatic extraction of chemical information from complicated datasets, machine learning in rotational spectra analysis revolutionizes the study of interstellar chemistry. It enables scientists to learn about the chemical diversity and development of interstellar regions, making crucial contributions to our comprehension of the genesis and development of the universe.
