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 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 absence of broad spectrum of wavelenth ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Molar absorbtivity is the measure of the None of these amount of light absorbed per unit concentration amount of light reflected and absorbed per unit concentration amount of light absorbed per unit length None of these amount of light absorbed per unit concentration amount of light reflected and absorbed per unit concentration amount of light absorbed per unit length 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 absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T cannot be measured as accurately as absorbance None of these Because %T is dependant on the power of the incident radiation Because absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T cannot be measured as accurately as absorbance None of these ANSWER DOWNLOAD EXAMIANS APP
