1. These absorptions can mask or confound the absorption spectrum of the sample. 2. Copper's absorption spectrum also falls within the range acceptable for SERS experiments. 3. Terahertz absorption spectrum in bulk GaAs computed using the THz Elliott formula. 4. For example, the absorption spectrum for water has its peak at around. 5. They also have differing fluorescence characteristics, but no discernible visible absorption spectrum . 6. Absorption spectrum analysis illustrates that zinc is the only cofactor present in barbiturase.7. Therefore, measurements of the absorption spectrum are used to determine these other properties. 8. The lower spectrum is the first derivative of the absorption spectrum . 9. The concentration of charge carriers influence the shape of the absorption spectrum considerably. 10. Light which has traversed a crystal of parisite exhibits a characteristic absorption spectrum .
