Spectroscopy Beer's Law states that absorbance is equal to P0 / P absorbance is proportional to the log of the concentration of the absorbing species None of these absorbance is proportional to both the path length and concentration of the absorbing species absorbance is equal to P0 / P absorbance is proportional to the log of the concentration of the absorbing species None of these absorbance is proportional to both the path length and concentration of the absorbing species 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 None of these the Fourier Transfer Algorithm allows us to scan all frequencies at once light is faster today that it used to be absence of broad spectrum of wavelenth None of these the Fourier Transfer Algorithm allows us to scan all frequencies at once 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 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 Because %T is dependant on the power of the incident radiation ANSWER DOWNLOAD EXAMIANS APP
