Investigating C-D out-of-plane vibrational modes in PAHs as a tool to study interstellar deuterium-containing PAHs
Mridusmita Buragohain, Takashi Onaka, Amit Pathak +2
Previous as well as recent observations by ISO, Spitzer, AKARI, SOFIA, JWST etc. have revealed various characteristics of mid-infrared emission bands between 3-20 micron. Subsequen…
Theoretical Investigation of Interstellar 3-Pyrroline: Formation, Rotational and Vibrational Spectroscopy
Anshika Pandey, Akant Vats, Satyam Srivastav +2
The recent detection of CN-functionalized aromatics partly addresses the long-standing mystery of the apparent absence of five- and six-membered rings in interstellar environments.…
A comprehensive rotational study of astronomical iso-pentane within 84 to 111 GHz
Anshika Pandey, Satyam Srivastav, Akant Vats +2
The rotational line survey by ALMA (Atacama Large Millimeter/submillimeter Array) recently revealed the presence of i-C3H7CN (i-PrCN) and n-C3H7CN (n-PrCN) in 3-mm atmospheric wind…
Rotational spectra of interstellar N- and CN-PAHs: pyrene and coronene
Akant Vats, Amit Pathak
The detection of benzonitrile (C6H5CN), 1- and 2-cyano-naphthalene (C10H7CN) in the cold, dark molecular cloud TMC-1 at centimetre (cm) wavelengths has opened up prospects for the…
Theoretical study of infrared spectra of interstellar PAH molecules with N, NH & NH incorporation
Akant Vats, Amit Pathak, Takashi Onaka +3
This work presents theoretical calculations of infrared spectra of nitrogen (N)-containing polycyclic aromatic hydrocarbon (PAH) molecules with incorporation of N, NH and NH us…
