Autor: Elsa Caytan, Romain Ligny, Jean-François Carpentier, Sophie M. Guillaume

Publikováno v: Polymers, Vol 10, Iss 5, p 533 (2018)

Band-selective (bs) HSQC, improving spectral resolution by restriction of the heteronuclear dimension without inducing spectral folding, has been recently used for polymer tacticity determination. Herein is reported an evaluation of various bs-HSQC a
