Gaseous HZnCl has been synthesized for the first time in a high-temperature tube furnace with a D.C. discharge of a flowing mixture of pure HCl and zinc vapor. The vibration-rotation emission spectrum of gaseous HZnCl was measured at high resolution using a Fourier transform spectrometer. The H-Zn stretching mode ( 1) of the H64Zn35Cl, H66Zn35Cl, H68Zn35Cl, and H64Zn37Cl species, as well as the 2 1 - 1 hot band of the most abundant isotopologue (H64Zn35Cl) were observed near 1966 cm-1. A least-squares fit was performed for each of four observed isotopologues and their spectroscopic constants were determined.
