摘要

Molecular relaxation processes in lithium (Li2CO3), sodium (Na2CO3), and potassium (K2CO3) carbonates are studied by Raman spectroscopy. It is found that the first-order structural phase transition in Li2CO3, Na2CO3, and K2CO3 carbonate crystals is extended. The existence of a pretransition region in the studied Li2CO3, Na2CO3, and K2CO3 carbonates is demonstrated.
