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 the Fourier Transfer Algorithm allows us to scan all frequencies at once None of these light is faster today that it used to be absence of broad spectrum of wavelenth the Fourier Transfer Algorithm allows us to scan all frequencies at once None of these light is faster today that it used to be absence of broad spectrum of wavelenth ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance? Because %T is dependant on the power of the incident radiation Because %T cannot be measured as accurately as absorbance None of these Because absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T is dependant on the power of the incident radiation Because %T cannot be measured as accurately as absorbance None of these Because absorbance is proportional to the concentration of the analyte, whereas %T is not ANSWER DOWNLOAD EXAMIANS APP
