Dispersed Fluorescence Spectroscopy of the ZnC2H5 Free Radical
Dispersed fluorescence spectra of the zinc monoethyl radical are presented. These have allowed vibrational frequencies of several modes in the ground electronic state of this molecule to be determined for the first time. In particular, substantial activity in both the Zn-C stretch and the Zn-C-C bend has been observed, with the frequencies for these modes being deduced as 387 and 180 cm-1, respectively. With the aid of the dispersed fluorescence data it has also proved possible to make reasonable assignments for several bands in the excitation spectrum. ZnC2H5 was prepared in these experiments by a dc electrical discharge through an argon/diethyl zinc mixture in a supersonic nozzle. Copyright 1997 Academic Press. Copyright 1997Academic Press
