Sentences with phrase «vibrational modes»

The water molecule has a permanent dipole moment which gives it a rotational mode that has an effect on most of the IR spectrum radiated by the Earth as well as vibrational modes that only operate on specific wavelengths.

But if the diamonds behaved as quantum mechanical objects, they would share one vibrational mode between them.

«The recorded images map the unique interaction between the different vibrational modes of the molecule and the varying enhanced electric fields sustained at different positions of the microscope's tip,» said Dr. Wayne P. Hess, a PNNL chemical physicist and co-author of the study.

«At the highest temperatures, the electron temperature is much higher than that of acoustic vibrational modes of the graphene lattice, so that less energy is needed to attain temperatures needed for visible light emission,» Myung - Ho Bae, a senior researcher at KRISS and co-lead author, observes.

From this it could be deduced how much the halogen ion is able to influence the neutral molecule prior to the substitution, either by orienting it or by exciting internal vibrational modes.

In particular, physicists don't fully understand the particles» three fundamental modes, which are analogous to the fundamental vibrational modes of a guitar string corresponding to different musical notes.

«Glass's off - kilter harmonies: New modeling method focuses attention on amorphous material's unusual vibrational modes.»

«Bond lengths and angles, as well as atomic vibrational modes, are variables supplied by the procedure.

Given that vibrational modes allow a molecule to absorb photons of corresponding (infrared) energies, isotopologues have different optical properties in the infrared range.

A convenient way to address it is to test for odor character differences between deuterated and undeuterated odorant isotopomers, since these have identical ground - state conformations but different vibrational modes.

Further, our study showed that the greater polarity in the bonds led to larger dipole derivatives in the C - F stretching vibrational modes, which leads to a quadratic increase in the IR intensity.

Steve: Hydrogen is H2 but once you start with CO2 or CH4 with methane or H2O and water vapor or O3 in ozone, the fact that you have three atoms in your molecule gives you a much wider variety of vibrational modes to...

Right: Scanning electron micrograph of a photonic crystal membrane, displaced according to one of the vibrational modes, with red and blue representing positive and negative displacement, respectively.

The scientists matched the vibrational modes of the club to the recorded sounds.

They carried out over 1000 measurements for every energy decay trace and were able to observe that as the energy of a vibrational mode decays, the rate of decay reaches a point where it changes abruptly to a lower value.

Using four vibrational modes, the device can attain a resolution of about 150 nanometers.

Consequently, isotopologues will have different sets of vibrational modes.

The vibrational modes of a molecule are determined by its shape and the masses of its constituent atoms.

In principle, odorant isotopomers provide a possible test of shape vs. vibration mechanisms: replacing, for example, hydrogen with deuterium in an odorant leaves the ground - state conformation of the molecule unaltered while doubling atomic mass and so altering the frequency of all its vibrational modes to a greater or lesser extent [11].

When upward radiation close to the right frequency hits a CO2 molecule, it can excite the vibrational mode at that frequency.

Even though CO2 has no dipole moment and some vibrational modes are IR inactive, some vibrations do cause a dipole and are IR active.
