Raman spectrum of cane-sugar crystal

Abstract

Using λ 2537 mercury resonance radiation as exciter, the Raman spectrum of cane-sugar crystal has been investigated. The recorded spectrum exhibits sixty-three Raman lines. Of these, the two intense Raman lines with frequency shifts 79 and 94 cm.−1 which are absent in the spectra of crystals ofα- andβ-glucose have been attributed to the mutual oscillations of the glucose and fructose units constituting the cane-sugar molecule. The C-H oscillations give rise to a group of ten closely spaced Raman lines.
