Shielding hyper-surfaces

There is also an immediate interest in coordinate derivatives of chemical shifts in situations where temperature effects, isotope chemical shifts, vibrational or rotational corrections are investigated. For these purposes chemical shielding hyper-surfaces have been calculated using ab initio methods (for a discussion see Jameson, Bennett and Raynes, Raynes and Bennett, Chesnut and Wright, de Dios et Sundholm et Sundholm and Gauss,and Auer et and the slope with respect to any internal... 

For and V l the shielding hyper-surfaces for the principal tensor components (Ta(, lA) and /i) have been worked out in some peptide...
