13 CO has a smaller force constant than 12 CO. 8.
Phosphorescence typically has a shorter lifetime than fluorescence.
In IR the fundamental modes of a molecule occur at energies greater than the corresponding overtone modes. A linear relationship usually exists between fluorescence intensity and concentration when the absorbance of the solution is less than .05. Short Answer 11. Derive Beer's Law. Consider the following normal vibrations of the linear molecule acetylene, C 2 H 2 .
