Some molecules in this set, such as CH 2 CHCH 2 C(CH 3 )HCN (2-methyl-4-pentenenitrile), exhibit branched alkyl chains with nitrile functional groups, which are significant for the synthesis of nitrogen-bearing organic compounds under interstellar conditions. Others, such as c-(N 2 CH)CHO (3H -diazirine-3-carbaldehyde), possess ring structures containing nitrogen atoms, which are particularly intriguing for their potential to form reactive intermediates in the ISM or CSE. Additionally, H 2 NCHCO (2-aminoethenone) and CH 2 NHCHCN are examples of small molecules with high astrophysical relevance due to their thermodynamic stability and favorable spectroscopic characteristics.
