Cryogenic-temperature (77 K) resonance Raman (RR) spectroscopy and 15N and 13C isotope substitutions were used to determine vibrational mode wavenumbers associated with CuIIÈCN-and CuIIÈSCN-units CuIIÈN 3 -, for azido, cyano and thiocyanato adducts of Pseudomonas aeruginosa Met121X (where X = Gly, A
