Laser Spectroscopy of Alkali Atom-Tetrahaloethylene Reactions.
Abstract
The results of a series of experiments are reported to determine the origin of the chemiluminescent spectrum observed in reactions of alkali metal atom swith vapors of C2C14 and similar halogenated C2 molecules. The emission was observed to be independent of the alkali atom and the halogen atom and, hence, attributed to a previously unobserved state of a carbon molecule, such as C2, C3, or C4. Null results from laser spectroscopy suggest the emission is not to the ground state of the molecule. Initial gain measurements were also negative. These reactions are being investigated using mass spectroscopy with the aim of determining the source of the chemiluminescence and the molecular dynamics of this and related reactions. During the course of this research, several other chemiluminescent reactions were discovered which are also promising candidates for future investigation. The primary result from this research is that the stripping of halogen atoms from parent molecules by alkali atoms is an exothermic process capable of producing electronically excited atoms and molecules and has apparently received little attention in the past.
