Chemical Evolution of Some Selected Complex Organic Molecules in Low-mass Star-forming Regions
The destiny of complex organic molecules (COMs) in star-forming regions is interlinked with various evolutionary phases. Therefore, identifying these species in diversified environments of identical star-forming regions would help to understand their ...

Fast prediction of anharmonic vibrational spectra for complex organic molecules
Interpreting Raman and IR vibrational spectra in complex organic molecules lacking symmetries poses a formidable challenge. In this study, we propose an innovative approach for simulating vibrational spectra and attributing observed peaks to molecular ...

Near-UV Spectrum of the Hexamethylenetetramine Cation
Hexamethylenetetramine (HMT; (CH _2 ) _6 N _4 ) is a complex cage-like molecule that forms by the reaction of ammonia with formaldehyde, two of the most prevalent components of ice mantles on interstellar dust grains.

Organic material in meteorites and the link to the origin of life
Life requires specific conditions that have been, so far, only proven to meet on Earth. Though the chemical elements required to form living organism (C, H, N, O, S, etc) are widespread in the universe, the molecules that are crucial for Life, like ...

Carbon Isotope Fractionation of Complex Organic Molecules in Star-forming Cores
Recent high-resolution and sensitivity Atacama Large Millimeter/submillimeter Array observations have unveiled the carbon isotope ratios ( ^12 C/ ^13 C) of complex organic molecules (COMs) in a low-mass protostellar source. To understand the ^12 C/ ^13 C
