It Remains a Cage: Ionization Tolerance of C60 Fullerene in Planetary Nebulae
SeyedAbdolreza Sadjadi, Quentin Andrew Parker
We demonstrate that by combining two robust theoretical quantum chemistry calculation techniques, stepwise ionization of C60 fullerene by UV and extreme UV photons can in principle…
A Theoretical Investigation of the Possible Detection of C24 in Space
SeyedAbdolreza Sadjadi, Sun Kwok, Franco Cataldo +2
Astronomical infrared spectral features at ~6.6, 9.8 and 20 micronm have recently been suggested as being due to the planar graphene form of C24 carbon cluster. Here we report dens…
The Astrochemistry Implications of Quantum Chemical Normal Modes Vibrational Analysis
SeyedAbdolreza Sadjadi, Quentin Andrew Parker
Understanding the molecular vibrations underlying each of the unknown infrared emission (UIE) bands (such as those found at 3.3, 3.4, 3.5, 6.2, 6.9, 7.7, 11.3, 15.8, 16.4, 18.9 mm)…
On the Origin of the 3.3 Micron Unidentified Infrared Emission Feature
Seyedabdolreza Sadjadi, Yong Zhang, Sun Kwok
The 3.3 m unidentified infrared emission feature is commonly attributed to C-H stretching band of aromatic molecules. Astronomical observations have shown that this feature is c…
A Theoretical Study on the Vibrational Spectra of PAH Molecules with Aliphatic Sidegroups
SeyedAbdolreza Sadjadi, Yong Zhang, Sun Kwok
The role of aliphatic side groups on the formation of astronomical unidentified infrared emission (UIE) features is investigated by applying the density functional theory (DFT) to…
