Spectroscopy Molar absorbtivity is the measure of the None of these amount of light reflected and absorbed per unit concentration amount of light absorbed per unit concentration amount of light absorbed per unit length None of these amount of light reflected and absorbed per unit concentration amount of light absorbed per unit concentration amount of light absorbed per unit length ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Which of the following relationships between absorbance and %transmittance is incorrect? A = 2 - log10 %T A = log10 1 / T A = log10 100 / %T All are correct A = 2 - log10 %T A = log10 1 / T A = log10 100 / %T All are correct ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance? 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 Because %T is dependant on the power of the incident radiation 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 the Fourier Transfer Algorithm allows us to scan all frequencies at once None of these absence of broad spectrum of wavelenth light is faster today that it used to be the Fourier Transfer Algorithm allows us to scan all frequencies at once None of these absence of broad spectrum of wavelenth light is faster today that it used to be ANSWER DOWNLOAD EXAMIANS APP
