Abstract
Laser-induced fluorescence has been used to make the first spectroscopic observation of the zinc monoethyl radical. This radical has been produced in a supersonic jet using electrical discharge fragmentation of zinc diethyl. The $\tilde{A}-\tilde{X}$ origin is significantly red-shifted from that of the related radical, zinc $monomethyl,^{1}$ explaining why previous attempts to observe this molecule were $unsuccessful.^{2}$ We have obtained both excitation and dispersed fluorescence spectra of $ZnC_{2}H_{3}$ and will present an assignment of the vibrational structure in these spectra. In addition, we will describe how a pulsed electrical discharge can be used to synthesise metal-containing radicals such as $ZnCH_{3}$ and $ZnC_{2}H_{3}$ by direct reaction involving metal atoms.
