Spectrophotometry is one of the most widely used methods to determine the of protein (or nucleic acid) present in a given solution by measuring the amount of light of a that is absorbed by that solution.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

they both have a y in them
