molecular vibration

Absorption of radiation is followed by molecular vibration to the S state.

But there are some molecular vibrations which cannot interact with this radiation.

The thing about molecular vibrations is that they have specific frequencies, called modes.

IR in particular is used to see atomic and molecular vibrations.

It is also possible to observe molecular vibrations by an inelastic scattering process.

In nonradiative or dark decay, energy is given off via molecular vibrations (heat).

The absorption of infrared light by organic molecules causes molecular vibrations.

It is important to realize that not all molecular vibrations lead to oscillating dipoles.

The radiation involved is normally of frequency much greater than that of any molecular vibration.

Infrared radiation corresponds to the energies associated primarily with molecular vibration.

Second derivatives also identify stationary points in molecular vibration.

In molecules with three or more atoms, the number of degrees of freedom for molecular vibrations is at least 3.

The water molecule has three fundamental molecular vibrations.

The frequencies of molecular vibrations range from less than 10 to approximately 10 Hz.

An assumption underlying these expressions is that the molecular vibration follows simple harmonic motion.

But for more complicated molecules we need to have a systematic way of working out how many of the molecular vibrations will be active.

Replies: Andy, Temperature is defined as molecular vibrations at an atomic level.

He also studied birefringence and molecular vibrations.

Will the molecular vibrations of heat make molecular machines unworkable or too unreliable for use?

The sparks and electrical flames created by his high-voltage coils were associated, he believed, with molecular vibrations in the air.

The infrared part of the electromagnetic spectrum covers molecular vibrations which can characterize chemical bonding within the sample.

Their 1928 paper considered the role of molecular vibrations in the transfer of energy between ultrasonic waves and gas molecules.

He investigated in particular the effect of hydrogen bonding on the anharmonicity of molecular vibrations.

A good way to look at this is to consider that molecular vibrations and rotations act as a 'heat sink' as the temperature decreases.

Perhaps surprisingly, molecular vibrations can be treated using Newtonian mechanics to calculate the correct vibration frequencies.
