摘要：

Laser excitation of Fe(CO)5, Cr(CO)6 and Mo(CO)6 in the region of the charge transfer bands around 2800 Å is found to produce Fe+, Cr+ and Mo+ with near unit efficiency in a laser flux as low as 108 W cm-2. The uncomplexed metal ion continues to dominate the photoion yield down to near threshold at a laser flux of 3 × 105 W cm-2. Excitation spectra of this photoion production indicate the absorption in this region is intrinsically diffuse. © 1979.
