Give the normal modes of vibrations of a triatomic linear and triatomic angular molecule with suitable diagrams.

Triatomic molecules can be categorized into linear and angular (non-linear) molecules based on their molecular geometry. Each type exhibits specific normal modes of vibrations that correspond to the motion of their atoms. Let's explore the normal modes of vibrations for both triatomic linear and angular molecules, along with suitable diagrams.

Triatomic Linear Molecule (e.g., Carbon Dioxide, CO2):

In a linear molecule, the atoms are arranged in a straight line. Carbon dioxide ______ _____ ________ _____ _________ ________ _______ ___ ______ _____ ________ ____.
