摘要：
Infrared (IR) multiphoton absorption and dissociation of difluorosilane molecules under the action of a pulsed transversely excited atmospheric CO2 laser were experimentally studied. It has been found that the multiphoton absorption is strongly saturated due to the rotational bottleneck effect. Isotope-selective IR multiphoton dissociation of difluorosilane was performed at 977.2 cm(-1). The dissociation rate for (SiH2F2)-Si-28 isotopomer has been found to be about twice as high as for the other isotopomers at this wavelength.
