  • Ab Initio Calculations of Conformational Effects on 13C NMR Spectra of Amorphous Polymers
    H.W. Spiess / R. Born
    In NMR, it is well-known that the chemical shift conveys structural informa­ tion, e. g. a carbonyl carbon will have a resonance frequency appreciably dif­ ferent from a methyl carbon, etc. The relation between structure and chemical shift is mostly established by empirical rules on the basis of prior experience. It is only quite recently that the adv...
