Adjective
of or relating to or characterized by vibration
Source: WordNetAll species of particles are unified in superstring theory since each arises from a different vibrational pattern executed by the same underlying entity. Brian Greene
Absorption bands in the infrared are due to modes of vibrational excitation in water vapor. Source: Internet
As these phenomena involve the movement of the atoms towards or away from each other, they can be interpreted as the coupling between the electronic and the vibrational states (i.e. the phonons) of the material. Source: Internet
A permanent dipole is not necessary, as the rule requires only a change in dipole moment. citation A molecule can vibrate in many ways, and each way is called a vibrational mode. Source: Internet
Around this time, intense theoretical group theory activity also predicted that C 60 should have only four IR-active vibrational bands, on account of its icosahedral symmetry. Source: Internet
Another factor is that the emission of fluorescence frequently leaves a fluorophore in a higher vibrational level of the ground state. Source: Internet
