在 Ar 和 CO2 气氛下，在 THF 中研究激光激发（355 nm）后 fac-Re(dmb)(CO)(3)(Et) 的瞬态 FT-IR 光谱。 Re(dmb(中心点))(CO)(3) (THF) 的 CO 伸缩带增长（2008 和 1897 cm(-1)），Re(dmb)(CO)(3)(Et) 漂白剂的 CO 伸缩带（1987 和 1875 cm(-1)）在 100 ms 时缓慢转化为格式复合物 Re(dmb)(CO)(3)(OC(O)H) (2020. 1916, 1873 和 1630 厘米(-1))。当溶剂稍湿时，在CO2下光解后也可观察到碳酸氢根配合物Re(dmb)(CO)(3)(OC(O)OH)。
Transient FT-IR spectra of fac-Re(dmb)(CO)(3)(Et) after laser excitation (355 nm) were investigated in THF under Ar and CO2 atmospheres. The CO stretching bands of Re(dmb(center dot))(CO)(3) (THF) grow (2008 and 1897 cm(-1)) and those of Re(dmb)(CO)(3)(Et) bleach (1987 and 1875 cm(-1)) at times 100 ms) converts slowly to the formato complex, Re(dmb)(CO)(3)(OC(O)H) (2020. 1916, 1873 and 1630 cm(-1)). When the solvent is slightly wet, the bicarbonato complex, Re(dmb)(CO)(3)(OC(O)OH), is also observed after photolysis under CO2.
