School Position: Senior Lecturer in Chemistry; Director of Teaching; Plagiarism and Collusion Officer; Chair, Chemistry Teaching Executive, member of the Wolfson Materials & Catalysis Centre.

Dr. Clayden studied for his B.A. in Chemistry at St Catherines College, Oxford University. Dr. Clayden's D. Phil., also from Oxford University, was concerned with shielding effects in NMR spectra and their use in conformational analysis. After a post-doctoral stint at MIT with Professor Waugh Dr. Clayden returned to Oxford University as a Shell Research Fellow. In 1986 Dr. Clayden joined ICI at the Wilton Research Centre where he managed a solid state NMR and materials NMR imaging. Dr. Clayden moved to UEA in 1994 where he is a member of the Molecular Structure Centre.

Nigel’s main interests lie in three areas. First, the characterisation of inorganic materials by solid state NMR methods. Thus, C-13 CPMAS demonstrates that halo alkyl phosphonates will react to incorporate imidazole and can be used in supported zirconium phosphonate catalysts. Second, the determination of protein dynamics through solution state NMR N-15 relaxation parameters. In the case of the in the E9 colicin system analysis of the relaxation data in the translocation domain has indicated local ordering around the TolB box. Third, the application of radio-frequency methods in µSR. In a recent experiment muon depolarisation of the FMuF state in SrF2 was studied using spin-locked muon polarisation and matched radiofrequency fields in the rotating frame.
