‘Imagine a molecule made up of tiny balls connected by springs, twang the balls and the molecule vibrates with a set of frequencies which can be recorded as a vibrational spectrum.’
‘In a rigid potential well, a molecule has a high vibrational frequency at room temperature, with a concomitant lower vibrational entropy.’
‘For a full exploitation of the information content of vibrational spectroscopy, quantum chemical calculations are necessary.’
‘The vibrational normal mode analysis has been carried out by solving the second-order derivations of the potential energy surface.’
‘Local defects tune the vibrational modes of carbon nanotubes’
