| Absorbance, emission, infrared, and Raman spectroscopy have been used to characterize expired and unexpired over the counter (OTC) medication. All spectra are measured with conventional instrumentation. However, fluorescence studies are conducted with a portable hand-held OceanOptics spectrofluorometer. And samples are excited with light emitting diodes, a green (532nm) or deep red (670nm) laser pointer. Temperature-dependent studies are employed to determine the shelf-life of OTC medication. Comparisons of expired and unexpired OTC medication spectral data and summary of our results are presented. |
