I. Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense) to each other than to those in other groups (clusters).It is a

Molecular vibrations are one of three different kinds of motion for molecules that include translational motion (when the whole molecule goes in the same direction) and rotational motion (when the molecule spins like a top). A vibrational motion for a molecule is when the bonds between atoms within a molecule move. Think of the atoms as round balls that are attached by a spring that can.
