Finding inspiration in the natural world and in science, she is fascinated by the vibrational frequencies of natural phenomena, ranging widely from the microscopic ( elements, DNA ) to the macroscopic ( body rhythms, water, stars, time ).

Briefly, replacing normal hydrogen ( protons ) by deuterium within a molecule causes the molecular vibrational frequency of X-H ( for example C-H, N-H and O-H ) bonds to decrease, which leads to a decrease in vibrational zero-point energy.

If the spontaneous decay rate is much smaller than the vibrational frequency of the atom in the trap, the energy levels of the system can be resolved as consisting of internal levels each corresponding to a ladder of vibrational states.

The vibrational frequency of the triple bond in benzyne was assigned by Rasziszhewski to be 1846 cm " 1, indicating a much weaker triple bond than in unstrained alkyne with vibrational frequency of approximately 2150 cm " 1.

The agreement in values is best for the energy at the bottom of the well that was evaluated at 3.15 eV . The fundamental vibrational frequencies for Xe Xe, is ? = 123 cm and for Xe Cl, ? = 180 cm.

When a light wave of a given frequency strikes a material with particles having the same or ( resonant ) vibrational frequencies, then those particles will absorb the energy of the light wave and transform it into thermal energy of vibrational motion.

In connection with other electronic and structural descriptors, such as the covalency metric or the distortion mode analysis from group theory, the A-B pair cophonicity is a guide to properly select either A or B atomic species to tune specific vibrational frequencies of a given system.

Hyperconjugation can be used for rationalizing a variety of other chemical phenomena, including the anomeric effect, the gauche effect, the rotational barrier of ethane, the beta-silicon effect, the vibrational frequency of exocyclic carbonyl groups, and the relative stability of substituted carbocations and substituted carbon centred steric hindrance.

One of the first working examples of a synthetic nanosensor was built by researchers at the Georgia Institute of Technology in 1999 . It involved attaching a single particle onto the end of a carbon nanotube and measuring the vibrational frequency of the nanotube both with and without the particle.
