Calculate the first two vibrational energy levels a diatomic molecule?

∙ 14y ago
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 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?
Vibrational.
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,
What is the potential energy surface of a molecule?
potential energy of a molecule is equivelent to the energy of the molecule in a fusion state
The thermal energy of an object is created by the?
Movement of particles
Why does reducing a molecule give that molecule greater potential energy?
Reducing the size of a molecule gives that molecule greater potential energy because the molecule isn't using that energy since it is smaller. Being larger would make less potential energy.
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.
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 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?
Vibrational.
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 happens when a diatomic molecule loses an electron Does the bond weaken?
No, it is not correct to say that the bond energy always decreases when a diatomic molecule loses an electron. F2 and O2 are counterexamples to this point. When a molecule loses an electron, it will come from the highest occupied molecular orbital. In both O2 and F2, this MO is an antibonding MO. Removing an electron from an antibonding MO *increases* the bond energy.
What is the formula for vibrational kinetic energy?
Vibrational kinetic energy is the energy due to vibrational motion :)
Which kind of energy is transferred between molecules of touching substances during conduction?
Vibrational energy. The vibration of one molecule is transferred to adjacent molecules as it "hits" them. The vibration of molecules is otherwise known as heat or thermal energy.
What ways can energy be stored?
There are five ways that energy can be stored in a molecule. They are mass energy, translational energy, bond energy, vibrational energy, rotational energy, and nuclear spin energy. All of these are considered to be potential energy, except for nuclear spin energy.
Bond length in a an Br2 molecule?
The bromine diatomic molecule has a bond energy of 190 kilojoules per mole. This translates to a bond length of 228 picometers.
How does thermal energy get passed in a conductor?
by transferring vibrational energy to adjacent molecules.
