Abstract
Emission and absorption spectra of oils (Mint species and Cymbopogan species) have been recorded in the visible and ultraviolet region using JY3CS spectrofluoremeter and Backman DU-70 spectrophotometer respectively. Our results show the presence of strong nonradiative state in the ultraviolet region. It is also found that the fluorescence intensity of these oils are comparable to that of Rh 6G dye in methanol solution. The main spectral features in the absorption spectra of mint species are found to be due to the absorption of menthol and menthone. Spearmint oil shows an extra absorption band which is not present in Japanese and Peppermint oils. (author). 7 refs, 2 figs.
