If no, what is the expectation value? (b) Is σ an eigenfunction of S.? If yes, what is the eigenvalue? If no, what is the expectation value?

Which of the following statements concerning spectroscopy is correct? A) Concentration of a solution is directly proportional to the % of photons transmitted. B) Salt plates are often used in IR spectroscopic measurements because they are transparent in that region.
