(a) 2D refocused INADEQUATE (J-mediated) 29Si{29Si} DQ NMR spectrum of as-synthesized zeolite ITW. (b) DNP-enhanced 2D 29Si{29Si} J-mediated correlation spectrum of calcined Si-SSZ-70. (c) Schematic diagram of the framework structure of Al-SSZ-70 (orange color indicates the T sites that are occupied by Al heteroatoms), and 2D 27Al{29Si} J-HMQC NMR spectrum of calcined Al-SSZ-70.
