Pleased to see the beautiful #MyACSCover of our review of stereoisomerISM published in @ACSPublications, with @MiguelSanzNovo (the artist!) and @DavidSAstro99. @C_Astrobiologia @CSIC

This review confirms that stereoisomerism is a fundamental contributor to interstellar molecular complexity.
It is already available in arXiv: arxiv.org/abs/2603.24848 ;
and it will appear soon in Open Access in the ACS Earth and Space Chemistry journal (@ACSPublications) (🧵4/4)

We have discussed the mechanisms that can explain the stereoisomeric ratios (OSR) - defined as the column density ratio of the higher-energy isomer divided by that of the lower-energy isomer (🧵3/4 ).

"INTERSTELLAR STEREOISOMERISM”: stereoisomers are molecules that share the same bonding arrangement, but differ in the three-dimensional orientation of their atoms. These are the 16 stereoisomeric pairs detected in the interstellar medium so far (🧵2/4 ):

🚨 NEW PUBLICATION 🚨
"INTERSTELLAR STEREOISOMERISM”: In this review done with @MiguelSanzNovo and @DavidSAstro99
we present the first comprehensive overview of stereoisomerism in the interstellar medium. @C_Astrobiologia

(3)🌌The molecule was identified in the Galactic center molecular cloud G+0.693–0.027, by combining ultra-deep astronomical observations from a large observational survey led by CAB (@ryvendel), with new laboratory experiments conducted at MPE (M. Araki, Valerio Lattanzi et al.)

🚨NEW RESULT!🚨 In a recent work led by @DavidSAstro99 we have detected for the first time in space the molecule H2CNCN (N-cyanomethanimine), the stable dimer of HCN of highest energy, and the most complex interstellar molecule containing the prebiotically relevant NCN backbone.
