Abstract
To help identify a novel emission feature extending from 550 nm to 880 nm produced in the gas-phase reaction of F2 with $CS_{2}$. the reaction of $F_{2}$ with $CS_{2}$ has been studied. This reaction yields a previously observed emission feature from SeF (A) extending from 500 nm to 870 nm and a banded feature between 350 and 500 nm that resembles fluorescence from $Se_{2}(A)$ but requires further analysis. An apparently new, broad feature extending from 600 nm to the near IR appears by itself under certain reaction conditions. This broad feature is unresolved at 0.1 nm resolution and is not very useful in understanding the $F_{2}/CS_{2}$ feature. Reactions of $F_{2}$ with $CH_{3} X CH_{3}$. where $X = Se, Se_{2}. Te$, and $Te_{2}$, are being studied as sources for emission spectra of $CH_{2}Se$ and $CH_{2}Te$. Fruitful chemical trends and analogies are being exploited in effort to identify new spectra of hard-to-study small molecules in chemiluminescence.
