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 None of these light is faster today that it used to be the Fourier Transfer Algorithm allows us to scan all frequencies at once absence of broad spectrum of wavelenth None of these light is faster today that it used to be the Fourier Transfer Algorithm allows us to scan all frequencies at once 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 None of these Because %T cannot be measured as accurately as absorbance 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 None of these Because %T cannot be measured as accurately as absorbance Because absorbance is proportional to the concentration of the analyte, whereas %T is not ANSWER DOWNLOAD EXAMIANS APP
