✦ Synopsis

A new method for preparing powders of very small particle size from vitrified dilute aqueous solutions is reported. In these powders particle size effects seem to be eliminated even for samples absorbing very strongly in the i.r. As an example the i.r. spectra of polycrystailine RbNO3 and CsNO3 and their temperature dependences are reported where "true" absorption spectra of the antisymmetric stretching transition seem to have been obtained.
