Abstract The first potential exoplanetary biosignature detections are likely to be ambiguous due the for false positives: abiotic planetary processes that produce observables similar those anticipated from a global biosphere. Here we propose class of methylated gases as corroborative “capstone” biosignatures. Capstone biosignatures metabolic products may less immediately detectable, but have su...

The reactivity of microsolvated fluoride ions, F (CH3OH)0–2, with methyl, ethyl, n-propyl, and t-butyl bromide is evaluated over a broad range of temperatures. Significant decreases in reactivity are observed as either solvation or temperature increases. Increasing solvation increases sensitivity to the reaction barrier as revealed by a larger temperature dependence. These reactions are dominat...
