Spectroscopy Beer's Law states that None of these absorbance is proportional to the log of the concentration of the absorbing species absorbance is proportional to both the path length and concentration of the absorbing species absorbance is equal to P0 / P None of these absorbance is proportional to the log of the concentration of the absorbing species absorbance is proportional to both the path length and concentration of the absorbing species absorbance is equal to P0 / P 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 None of these Because %T cannot be measured as accurately as absorbance 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 None of these Because %T cannot be measured as accurately as absorbance 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 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 absence of broad spectrum of wavelenth None of these ANSWER DOWNLOAD EXAMIANS APP
