The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

The vacuum-ultraviolet (VUV) absorption and fluorescence spectroscopy of CF2X2 was studied. Photoexcitation energies in a wide range were employed due to the versatility of the synchrotron radiation source. The electron peaks were assigned to Rydberg transitions in the VUV absorption spectra of CF2X2. Minor electron channels were represented by the photodissociation to emitting states of fragment species. Results depicted that the small size of hydrogen atom was related to the anomalous behavior of CF2H2 in forming H-H or H-F bonds in unimolecular fragmentation process.
