[astro-ph.GA] We report the laboratory characterization of the higher-energy isomer of propenethial, syn-CH2CHCHS. While the lower-energy isomer, anti-CH2CHCHS, was detected in the interstellar medium during the QUIJOTE line survey of […]
![Molecular structure of the two conformational isomers that are connected through a single bond rotation,syn and anti CH2CHCHS. The numbers represent the zero-point energy corrected energy separation in kcal mol−1 at the CCSD(T)-F12/cc-pVTZ-F12//SCS-MP2/aug-cc-pVTZ, described later in the text. -- [astro-ph.GA]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/Laboratory-spectroscopy.png?resize=1200%2C723&ssl=1)
