Evidence for correlations at the interface between the ZIF-8 and IG components in the composite were provided by multidimensional multinuclear magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy, which is well equipped to probe spatial proximities. This approach is strongly suited to glass-containing systems given that NMR is not dependent on the presence of long range order but on nuclear spin interactions between NMR-active nuclei that are plentiful in the MOF-CIGC targeted here. In particular, this work focuses on very sensitive spin 1/2 nuclei (high natural abundance, high Larmor frequency) for each of the individual components of the MOF-CIGC components, namely 1 H and P from the ZIF-8 and IG glasses, respectively. NMR spectra of other active nuclei ( 13 C, N, both spin ½; Na quadrupolar nucleus with spin 3/2; and 67 Zn spin 5/2) were also obtained to identify potential Zn
