Yes, molecular vibrations can be controlled by various means, such as using external fields, chemical modifications, or nanoconfinement. For instance, applying an electric or magnetic field can influence the vibrational states of molecules. Chemical modifications, such as attaching functional groups, can alter vibrational frequencies. Nanoconfinement, where molecules are restricted in nanoscale environments, can also significantly affect their vibrational behavior. These techniques are used to tailor the properties of nanomaterials for specific applications.
