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 absence of broad spectrum of wavelenth the Fourier Transfer Algorithm allows us to scan all frequencies at once light is faster today that it used to be None of these absence of broad spectrum of wavelenth the Fourier Transfer Algorithm allows us to scan all frequencies at once light is faster today that it used to be None of these ANSWER DOWNLOAD EXAMIANS APP
