Answer:
1 Zero-point energy (ZPE) is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle. ... All these fields have zero-point energy.
2.Zero-point energy is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle.
3.Raman spectroscopy is less restrictive than pure rotational spectroscopy: Linear symmetric molecules do have rotational Raman spectra. ) do not have pure rotational spectra (do not possess permanent dipole moments). still do not have rotational Raman spectra as they do not have an anisotropic polarizability.
4.Raman spectroscopy; is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified.
