What are the vibrational normal modes of a molecule and how do they contribute to its overall structure and properties?
The vibrational normal modes of a molecule are specific patterns of motion in which atoms move relative to each other. These modes represent the different ways a molecule can vibrate, such as stretching, bending, or twisting. The vibrational normal modes contribute to a molecule's overall structure and properties by affecting its stability, reactivity, and spectroscopic behavior. By studying these modes, scientists can gain insights into the molecular structure and behavior of a substance.

In molecular motion and vibrational analysis, the significance of 3n-6 degrees of freedom refers to the number of ways a molecule can move and vibrate in space. This formula accounts for the three translational and three rotational degrees of freedom that all molecules have, as well as the 6 constraints imposed by the molecule's structure. This calculation helps determine the number of vibrational modes a molecule can have, which is important for understanding its behavior and properties.
