DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Section cross-reference(s): 80 The possibility of positional isomer sepn.There are some reagents with their cas registry numbers 433-19-2 and 402-31-3 are used in this study. induced by radiation of an IR free electron laser has been demonstrated. Expts. were carried out in 1:1 mixt. of para- and meta-hexafluoroxylenes in gaseous phase. Wide tunability of free electron laser allowed for enrichment of the reaction mixt. either by meta- or para-isomer. The max. isomer selectivity achieved, defined as a ratio of dissocn. yields per laser pulse of corresponding species, was > 300. .
