Laboratory Evidence that Methanol-Rich Ice Mantles Lower Methyl Formate Binding Energies
[astro-ph.IM] Complex organic molecules are widely detected in star-forming regions and are important precursors to prebiotic species. Because these molecules are thought to form primarily within icy grain mantles, their […]
