Calcite an overview ScienceDirect Topics

Calcite is the most stable form of calcium carbonate Samples of 13 Cenriched calcite have been studied by Phillips and coworkers 74 The variation of the 13 C CPMAS signal as a function of the contact time resembles closely to what expected for an isolated 13 C– 1 H spin pair and therefore the extracted internuclear distance 19 ± 01 Å provides a strong evidence for the presence of bicarbonate defects
