The vibrational energy of a diatomic molecule can be approximated by extension of the quantum harmonic oscillator. The vibrational energy, Ev, is then Ev = (v + 1/2)hv0 where v is an integer representing vibrational quantum numbers such that v = 0,1,2,3,..., where v=0 for a diatomic molecule at the ground vibrational state; h is Planck's constant; and v0 is the fundamental vibrational frequency. For this problem then, you would need the fundamental vibrational frequency of the particular diatomic atom, and then simply calculate Ev for v=1, and v=2.

What are vibrational and rotational quantum number?
Vibrational quantum number indicates the vibrational energy level of a molecule, while rotational quantum number describes the rotational energy level. Both quantum numbers are used to describe the quantized energy states of a molecule in quantum mechanics.
What is a form of kinetic energy that occurs within a molecule when the bonds are stretched or bent a translational b rotational c vibrational d internal?
c. Vibrational energy occurs within a molecule when the bonds are stretched or bent. This type of energy is associated with the movement of atoms within a molecule as they vibrate about their equilibrium positions.
What is bigger a oxygen molecule or a mitochondria?
A mitochondrion is much larger than an oxygen molecule. Mitochondria are organelles found within cells that generate energy, while an oxygen molecule is a diatomic molecule composed of two oxygen atoms.
Why does the double bond between two carbon atoms absorb ir energy?
Infrared is absorbed by the vibration of molecules. The vibrational energy of a molecule is quantized. The IR energy will cause vibration of the atoms linked by the bond. This will be a specific frequency that will vary slightly from compound to compound.ecule,
When an color photon is emitted from some molecule that means molecule jumped from some energy level to lower and emitted it or just one of its atom's electron did?
Either scenario is possible. Some electrons are involved in covalent bonds and have an emission spectrum that depicts that extended commitment. Some electrons are more tightly involved with individual atoms and their emissions are of higher energies.
What is the significance of vibrational degrees of freedom in a diatomic molecule?
The vibrational degrees of freedom in a diatomic molecule refer to the ways in which the atoms in the molecule can vibrate relative to each other. These vibrations play a crucial role in determining the molecule's energy levels and overall behavior. By studying these vibrational modes, scientists can gain insights into the molecule's structure, stability, and reactivity.
Write the vibrational energy equation which contributes to the internal energy of a molecule?
Molecular vibrations are one of the ways in which a molecule stores chemical energy. For a diatomic molecule, the vibrational can be approximated by the quantum harmonic oscillator. The vibrational energy Ev is Ev = (v + 1/2)hv0 where v is an integer representing vibrational quantum numbers such that v = 0,1,2,3,..., where v=0 for a diatomic molecule at the ground vibrational state; h is Planck's constant; and v0 is the natural frequency of the harmonic oscillator.
What is the significance of the degrees of freedom in a diatomic molecule?
The degrees of freedom in a diatomic molecule represent the number of ways the molecule can move and store energy. In a diatomic molecule, there are three degrees of freedom: translational, rotational, and vibrational. These degrees of freedom are important because they determine the molecule's ability to store and release energy, which affects its behavior and properties.
How do vibrational degrees of freedom manifest in a diatomic molecule?
In a diatomic molecule, vibrational degrees of freedom manifest as the molecule's ability to vibrate along its bond axis. This vibration occurs as the bond length changes, causing the atoms to move closer together and farther apart. The energy associated with these vibrations is quantized, meaning it can only take on certain discrete values.
Which vibrational modes are affected when a molecule absorbs infrared electromagnetic energy?
When a molecule absorbs infrared electromagnetic energy, it affects the vibrational modes of the molecule.
What are vibrational and rotational quantum number?
Vibrational quantum number indicates the vibrational energy level of a molecule, while rotational quantum number describes the rotational energy level. Both quantum numbers are used to describe the quantized energy states of a molecule in quantum mechanics.
What is a form of kinetic energy that occurs within a molecule when the bonds are stretched or bent a translational b rotational c vibrational d internal?
c. Vibrational energy occurs within a molecule when the bonds are stretched or bent. This type of energy is associated with the movement of atoms within a molecule as they vibrate about their equilibrium positions.
Can molecule have zero vibrational energy?
No. From what I understand, the Uncertainty Principle won't allow this - so even at absolute zero (a temperature that can't really be achieved 100%), there will still be some vibrational energy left.
What has the author R J Le Roy written?
R. J. Le Roy has written: 'Dissociation energy and long-range potential of diatomic molecules from vibrational spacings'
Why is the specific heat of poly atomic gases is higher than that of mono atomic gases?
Diatomic gases can absorb heat to increase their vibrational and rotational energy in addition to their translational energy. Monatomic gases have no bonds to vibrate or rotate.
How fast does a molecule have to vibrate to create the color red?
Visible spectra are associated with electron energy state transitions; vibrational modes show up in the infrared. If you're asking about black body radiation then you can use the Maxwell-Boltzmann equation to calculate the temperature.
What is the total energy of motion in a molecule?
The total energy of motion in a molecule is referred to as its kinetic energy. This includes the energy associated with the molecule's translational, rotational, and vibrational motion. Temperature is a measure of the average kinetic energy of molecules in a substance.
