Fig. 5: SSNMR spectra of PEI@HP20 with guest gases.
From: Benchmarking selective capture of trace CO2 from C2H2 using an amine-functionalized adsorbent
In situ static VT 2H and 13C SSNMR spectra of PEI@HP20 loaded with saturated C2D2 (a) and 13CO2 (b) along with simulations (see the corresponding top legend). c 13C CP/MAS SSNMR spectrum of PEI@HP20 − 13CO2. The * symbols denote spinning sidebands. d 1H MAS SSNMR spectra of PEI@HP20 and PEI@HP20 − 13CO2. The different colored resonances beneath the experimental spectra are deconvolutions of individual signal contributions to the overall 1H SSNMR spectra. e 1H → 13C HETCOR spectra and correlation assignments. The static VT 2H SSNMR spectra of PEI@HP20-C2D2 were collected at a magnetic field strength of 9.4 T, with the other measurements obtained at a magnetic field strength of 14.1 T.
