(RR) spectra of five-coordinate dioxygen adducts of cobalt(tetramesitylporphine) and cobalt(tetramesopropylporphine) formed in low temperature O2 matrices are reported. For the first time, all three vibrations expected for the Co–O2 fragment, ν(O–O), ν(Co–O2) and δ(Co–O–O), were observed for 16O2 and 18O2 isotopomers. These bands have been assigned based on oxygen isotope shift data as well as normal coordinate
