In the figure below you see a schematic view of a double beam spectrophotometer.
a) Name and describe all numbered components well!
b) Describe by formula how to calculate the transmittance (T) of a sample using P0 and P! and If the transmittance is measured to be 10%, what is the absorbance of the sample?
c) You analyze a sample with nitrate ions and read an absorbance of 0.350. The width of the cuvette is 1 cm and the molar absorptivity is 6400 M-1 cm-1. What is the concentration of the nitrate ions in the sample. Enter the name of the relationship you are using to calculate your concentration.
d) In spectroscopic measurements, the samples are illuminated with a light in the visible or ultraviolet spectrum. What happens in the molecule when this light hits it. State what happens if the sample is instead illuminated by a light with an even shorter wavelength.
