A study of the structure and dynamics of the hydronium ion by high resolution infrared laser spectroscopy. III. The v3 band of D 3O+
Abstract
294 transitions were measured by velocity modulation spectroscopy using a difference frequency laser system with a D2/O2 discharge and assigned to the v3 (antisymmetric stretch) band of D 3O+. A simultaneous analysis of this data with the v 2 band spectra reported by Sears et al. [J. Chem. Phys. 83, 2676 (1985)] yielded a refined set of parameters for both the ground and the excited states of both bands. The v3 bandcenters are 2629.6512(39) and 2624.2376(47) cm-1 for the s-s and a-a inversion components, respectively. © 1990 American Institute of Physics.
