What are the two primary types of vibrational modes in molecules?
Understand the Problem
The question is asking about the two main categories of vibrational modes that molecules can exhibit, which generally refers to the types of motions that the atoms within a molecule can undergo when they vibrate.
Answer
Stretching vibrations and bending vibrations.
The two primary types of vibrational modes in molecules are stretching vibrations and bending vibrations.
Answer for screen readers
The two primary types of vibrational modes in molecules are stretching vibrations and bending vibrations.
More Information
Vibrational modes are the characteristic movements of atoms in a molecule. Stretching involves changes in bond length, while bending involves changes in bond angles. These modes are significant in vibrational spectroscopy, such as IR and Raman spectroscopy, which analyze molecular vibrations.
