摘要: The molecular ion H3+ is considered the cornerstone of interstellar chemistry because it initiates reactions responsible for production many larger molecules. Recently discovered in dense clouds, has now been observed diffuse medium toward Cygnus OB2 No. 12. Analysis suggests that high column density (3.8 × 1014 per square centimeter) due not to a concentration but long absorption path. This and other work demonstrate ubiquity its potential as probe physical chemical conditions medium.
