		In Quantum Sound Therapy the harmony is re-instated through induction as all molecules are moved to the same tune by the vibrations of the special sounds in the music used.
		The rate of vibration (frequency) determined the characteristics of that energy, and the mind was that with which we controlled the frequency.
		Both the bed and the chair are designed to induce the experience of quantum vibration in the individual who is having the session.

	QM Tutorial: harmonic oscillator
		Each molecular vibration therefore has a minimum energy, even at a temperature of 0 K. The vibrational ground state v=0 therefore often is called zero point vibration.
		Vibrations that do not involve hydrogen atoms occur at significantly lower frequencies, because of the significantly larger reduced mass.
		Since the energy difference between all neighbouring energy levels is identical, the spectrum of a harmonic oscillator would contain only a single line for each vibration mode.

		One also notes that not all the ground state vibrational energy is available to be added to the translational energy to cross the energy barrier.
		=0 vibrational state energy of 6.2 kcal gives a total energy of 11.89 kcal which is greater than barrier height of 9.13 kcal.
		The minimum kinetic energy 5.69 kcal is not sufficient to cross the potential energy barrier of 9.13 kcal and requires some of the vibrational energy from the BC molecules.

	Molecular Physics and Astrophysics
		The transition from normal mode to local mode is a manifestation of the mixing between vibrational states which also leads to the concept of polyads.
		A vibration localized in a single OH bond is called a local mode.
		Hence the degeneracy in the vibrational and rotational states is lifted resulting in many allowed transitions.

	CO2
		The Carbon-Dioxide laser is a particularly excellent example because it so clearly demonstrates the characteristics of a molecular laser and as well as the dynamics of molecular vibration and rotation.
		In the case of molecular vibration, if one atom of a molecule is oscillating with some period then it cause a corresponding oscillation in the other atoms- the same resonant effect observed in the classical system of two masses connected by a spring.
		Resonance is found in these molecular vibrations which occur because the relative positions and orientations of the atomic nuclei are not absolutely fixed within the molecule.

	Born-Oppenheimer approximation - Wikipedia, the free encyclopedia
		This basis set is defined as the direct product of the eigenfunctions of the electronic molecular Hamiltonian times functions depending on the molecular geometry only and describing the vibration and dissociation of the molecule.
		The Born-Oppenheimer approximation consists in replacing the electronic molecular Hamiltonian in the molecular Hamiltonian by its eigenvalues (which are adiabatically dependent of the molecular geometry) called in this context potential energy surfaces.
		The Born-Oppenheimer approximation is a good one, and has become a routine foundation stone for the physical study of solid and molecular systems.

	That’s impossible
		Thermal noise, the vibration and motion of atoms and molecules caused by the fact that they have a temperature above absolute zero, is indeed a constraint on molecular machine design, but poses no insurmountable (or even conceptually very difficult) challenges.
		While concerns about thermal noise and quantum effects form the basis for most of the sweeping arguments against the feasibility of molecular machines, a lesser argument is “You can’t provide power.” This argument is seen less often because it is fairly obvious that power does not create a fundamental problem.
		In short, the unfamiliarity of the intellectual terrain, coupled with the existence of designs that don’t work, confuses the new comer.The existence of effective molecular designs is obscured by the many ways in which it’s possible to fail.

		The most compact argument showing that thermal noise is not incompatible with the existence of molecular machines is the existence of a vast assortment of biological molecular machines, including the ribosome (which can translate mRNA instructions into proteins), molecular motors, and the like.

	SOUND
		Sound is a molecular disturbance and the disturbance is caused by a vibration.
		Notice that heavier molecules which are more resistant to disturbance, transmit sound waves more slowly, e.g., sound travels more slowly in carbon dioxide (molecular mass 44) than oxgygen (molecular mass 32), and in lead (atomic mass 207) than copper (atomic mass 64).
		The sounds we hear in our daily life commence as a vibration in an object, it may the plucked string of a guitar, the diaphragm in a loud-speaker, the vocal chords, a bell or whatever.

		It is conventional to examine the rotational movement of a hypothetical "rigid" molecule as well as the vibrational motion of a non-rotating molecule, and to then treat the rotation-vibration couplings using perturbation theory.

		Each of these normal vibrational modes contributes RT to the average molar energy of the substance and is a primary reason why heat capacities increase with molecular complexity.
		A linear molecular has two such qualified rotations (rotation around the molecular axis does not qualify as the atoms are located directly on the rotation axis) and its average molar energy stored in rotational motion is
		You will be looking at the increasing numbers and features of the normal modes of vibration as molecules become larger in size and more complex in their structure.

	Rockefeller University scientists take on controversial 'vibration theory' of smell
		The final experiment, a test of both the shape and vibration theory, is based on Turin's proposal that two chemicals that have almost identical shapes (acetophenone and deuterated acetophenone) have markedly different molecular vibrations and therefore distinct smells.
		Andreas Keller, Ph.D., a postdoctoral fellow in Vosshall's lab, conducted a series of experiments that the principle proponent of vibration theory, the biophysicist Luca Turin, Ph.D., said would prove that his theory is correct.
		The findings are important in the sometimes contentious field of smell research because it is the first time vibration theory has actually been put to the rigor of a controlled and double-blind human test, the Rockefeller researchers say.

		Laser Stark spectroscopy utilizes the Stark effect to shift transitions betweeen molecular rotation (vibration-rotation or torsion-rotation) energy levels into resonance with lasers whose frequencies are close to the zero-field transition frequency.
		Since then, the Stark effect has played an important role in the investigation of atomic and molecular spectra and has provided the most precise information available about molecular structures and electric dipole moments.
		In laser Stark spectroscopy, a 4-meter (13-foot) long direct discharge gas laser is used to record the high-resolution Stark spectra of molecules in the far-infrared (FIR) region.
