摘要: The electric field arising from K+ or Na+ in the “A” sites of synthetic hydroxyamphiboles richterite-tremolite series raises stretching frequency adjacent OH groups by about 60 cm−1. In natural amphiboles, however, increase is generally only 20–40 cm−1, due, probably, to effects such substitutions as F for and Al Si.
