  • Harmonic function and vibrational energy states

    More than two atoms in a molecule give rise to several minima points about which motion can occur, so it is possible for a molecule to have several harmonic modes of motion at the same time.

  • UV/Visible and IR spectroscopy

    The IR spectrum for polystyrene shows lots of sharp peaks due to lot of absorptions. This can be explained on the basis of number of vibrational modes for the given polystyrene sample. Suppose 100,000gm /mole sample of polystyrene.

  • Unzipping of a DNA molecule as a function of temperature

    E.g. if nz is large, which means that the molecule has unzipped by a large amount, then that will affect the energy levels of the vibrational modes.

  • Organic Compound Analyzed using UV specro and IR Spectro

    However, in IR spectra we are observing the vibrational modes of a molecule which can be many in number and complex. Many localized vibrations are very useful for the identification of functional groups.

  • Fractional excitation of a two-state ensemble

    with v (wavenumber)= 30 cm-1 Based upon these calculations, is it reasonable to assume that essentially any molecule a photon encounters in the body will be in its ground vibrational state?

  • Degrees of freedom of diatomic molecule and Fermi energy

    If the temperature is so high that the vibrational degree of freedom can be treated classically, then it makes a contribution of k T and not 102 k T, as there is a potential energy and a kinetic energy component here, both of which make a contribution
