We investigated the relation between Sr# [= 100 Sr/(Sr + Ca) in mol] of calcites and their Raman spectra for Sr‐doped calcite samples with Sr# of 0–13.2. We selected 3 major Raman peaks observed at 150–155 cm−1 (peak A), 274–282 cm−1 (peak B), and 710–712.5 cm−1 (peak C). With increasing Sr#, the peaks shifted monotonously to lower wavenumbers. We obtained a linear expression for peak B as Sr# = −1.734 ΔνB + 76.93, where ΔνB is a separation between peak B and a neon emission line of 237.07 cm−1 in Raman shift. The present spectroscopic analysis can ascertain Sr# of calcite with precision of ±1.26 in the range of Sr# of 0–13.2.
