Popis: | Photo-chemical processes in hot neutral gas are summarized that are likely responsible for the destruction and formation of observed molecules in planetary nebulae. According to the hot gas scenario, detected simple molecules such as CN, HCN, C2H, and HCO+ are destroyed in a matter of a week, but are constantly and quickly re-formed. |
