Bet Method

Changes in the Raman spectrum of pyridine on a silica surface with increasing surface coverage may be used to determine the monolayer capacity. The method, which is independent of the BET method, produces a result which is in quantitative agreement with the BET result.

Infra Red

The infra-red absorption spectrum and laser raman spectrum of crystalline potassium trichromate are reported and compared with the corresponding spectra of potassium dichromate. It is shown that the state of aggregation of acid and concentrated aqueous chromate solutions can be investigated by use of laser raman spectroscopy. Trichromate ions are found to exist in acid dichromate solutions having concentrations ≧ 3 M and acidity pH ≪ 0, and in aqueous solutions of chromium trioxide provided concenrations are ≧ 2 M.
