Abstract
We report the infrared spectrum of the silicon hydride cluster ion SiH7+ obtained by vibrational predissociation spectroscopy. SiH7+ ions were excited by a tunable infrared laser, and the resulting SiH5+ photofragment intensity was measured as a function of the laser wavelength. We observed a vibrational band centered at 3866 cm-1, which we assigned as a perturbed H2 stretch. The absence of a second band between 3500 and 4200 cm-1 suggests that the ion forms a symmetric complex with the structure H2·SiH3+·H2, in contrast to the species CH7+, which has the structure CH5+·H2.
