Demonstrative ¹³C NMR of 20 μl of glycerol and 75 psig O₂ reacted over 50.1 mg dehydrated ZrO₂ at 175 °C with and without magic angle spinning (left) and cartoos of the rotor and approximate contents inside the coil and magneti field (right). The static spectrum was acquired with 12,000 scans and the spinning was collected with 32,000 scans. The NMR rotor representation was created using Solidworks (www.solidworks.com).
