Spectroscopy Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance? Because %T cannot be measured as accurately as absorbance Because absorbance is proportional to the concentration of the analyte, whereas %T is not None of these Because %T is dependant on the power of the incident radiation Because %T cannot be measured as accurately as absorbance Because absorbance is proportional to the concentration of the analyte, whereas %T is not None of these Because %T is dependant on the power of the incident radiation ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy In the past, IR spectra had to be aquired one wavelength at a time, which took a long time. Today quick spectra is due to the light is faster today that it used to be None of these the Fourier Transfer Algorithm allows us to scan all frequencies at once absence of broad spectrum of wavelenth light is faster today that it used to be None of these the Fourier Transfer Algorithm allows us to scan all frequencies at once absence of broad spectrum of wavelenth ANSWER DOWNLOAD EXAMIANS APP
