Series UV-vis-NIR Spectrophotometer in the range 175-3300 nm. Fourier Transform infrared (FTIR) spectra were recorded as microcrystalline powders using a Bruker Tensor 27 spectrometer (ATR) or as Nujol mulls in KBr discs on a Perkin Elmer Spectrum RX1 spectrometer located within a nitrogen-filled glovebox. The FTIR spectra have been normalized to 0.4 absorbance for the peak at ~1460 cm -1 (100-39.8% transmittance). Elemental analysis samples were prepared in an argon-filled glovebox and the analyses carried out by Mr Martin Jennings and Mrs Anne Davies at the Microanalytical service, School of Chemistry, The University of Manchester.
