Ramanite-(Cs) (original) (raw)

A valid IMA mineral species

Formula:

Cs[B5O6(OH)4] · 2H2O

Specific Gravity:

2.230 (Calculated)

Crystal System:

Monoclinic

Name:

Named in honor of Sir Chandrasekhara Venkata Raman (7 November 1888, Thiruvanaikoil, Tiruchirappalli, Madras Presidency, British India - 21 November 1970, Bangalore, Karnataka, India), physicist. He was awarded the 1930 Nobel Prize for Physics for discovering what is now called Raman scattering. Raman spectroscopy is based on this effect and is now an important tool for mineral identification, and was critical for the discovery of this mineral.
