“…The Rh center in the CpRh(CO) transient 7 absorbing at 1985 cm -1 also appears to contain a partial negative charge. The same conclusion can be reached for CpRh(CO) 2 and CpIr(CO) 2 where C-O stretching frequencies [39][40][41] are some 55 cm -1 lower than neon matrix frequencies for Rh(CO) 2 (2031 cm -1 ) and Ir(CO) 2 (2014 cm -1 ).…”

“…TRIR experiments monitoring the photolysis of Rh(Cp)(CO) 2 in solution by Perutz and co-workers has characterised the unstable alkyl hydride complex, Rh(Cp)(CO)(C 6 H 11 )H, at room temperature [37]. Bergman and co-workers investigated the photolysis of Rh(Cp*)(CO) 2 in low temperature noble gas solutions, doped with alkanes, with TRIR spectroscopy and found evidence for the presence of an organometallic alkane complex as a precursor to C-H activation.…”

“…N o other strong product bands were observed immediately after photolysis, al- though weaker bands at 1963 and 2035 cm-' were noted. O n the basis of work in matrices (12) and in'liquid Kr (7,13,14), it is reasonable that the 1985 cm-' band arises from the unsolvated monocarbonyl CpRh(C0) (compound 2 in Fig. 1).…”
