Hot band, the Glossary

In molecular vibrational spectroscopy, a hot band is a band centred on a hot transition, which is a transition between two excited vibrational states, i.e. neither is the overall ground state.^[1]

Allyn & Bacon

Allyn & Bacon, founded in 1868, is a higher education textbook publisher in the areas of education, humanities and social sciences.

Boltzmann constant

The Boltzmann constant is the proportionality factor that relates the average relative thermal energy of particles in a gas with the thermodynamic temperature of the gas.

See Hot band and Boltzmann constant

In statistical mechanics and mathematics, a Boltzmann distribution (also called Gibbs distribution Translated by J.B. Sykes and M.J. Kearsley. See section 28) is a probability distribution or probability measure that gives the probability that a system will be in a certain state as a function of that state's energy and the temperature of the system.

See Hot band and Boltzmann distribution

Excited state

In quantum mechanics, an excited state of a system (such as an atom, molecule or nucleus) is any quantum state of the system that has a higher energy than the ground state (that is, more energy than the absolute minimum).

See Hot band and Excited state

Ground state

The ground state of a quantum-mechanical system is its stationary state of lowest energy; the energy of the ground state is known as the zero-point energy of the system.

See Hot band and Ground state

Harmonic oscillator

In classical mechanics, a harmonic oscillator is a system that, when displaced from its equilibrium position, experiences a restoring force F proportional to the displacement x: \vec F.

See Hot band and Harmonic oscillator

Infrared spectroscopy

Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. Hot band and infrared spectroscopy are vibrational spectroscopy.

See Hot band and Infrared spectroscopy

Molecular vibration

A molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged.

See Hot band and Molecular vibration

Normal mode

A normal mode of a dynamical system is a pattern of motion in which all parts of the system move sinusoidally with the same frequency and with a fixed phase relation.

See Hot band and Normal mode

Overtone

An overtone is any resonant frequency above the fundamental frequency of a sound.

See Hot band and Overtone

Quantum harmonic oscillator

The quantum harmonic oscillator is the quantum-mechanical analog of the classical harmonic oscillator.

See Hot band and Quantum harmonic oscillator

Quantum number

In quantum physics and chemistry, quantum numbers are quantities that characterize the possible states of the system.

See Hot band and Quantum number

Raman spectroscopy

Raman spectroscopy (named after physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Hot band and Raman spectroscopy are vibrational spectroscopy.

See Hot band and Raman spectroscopy

Redshift

In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light).

See Hot band and Redshift

Selection rule

In physics and chemistry, a selection rule, or transition rule, formally constrains the possible transitions of a system from one quantum state to another.

See Hot band and Selection rule
