Dipole moments play a critical role in the detectability of molecules through rotational spectroscopy, as higher dipole moments enhance the intensity of spectral transitions. All analyzed molecules exhibit at least one conformation with a dipole moment exceeding 1.50 Debye, with some reaching values as high as 6 Debye (Table ). Molecules such as 1 (N -methyleneformamide), 2 (imine acetaldehyde), 3 (oxiran-2-ylazanide), and 6 (2-aminoethenone) stand out due to their high dipole moments, making them strong candidates for detection in the ISM or circumstellar envelopes (CSE). These properties suggest that rotational spectroscopy is particularly suitable for identifying these molecules in interstellar environments.
