In a diagram of an anharmonic oscillator eventually the A-B bond breaks, this is known as ...... and is given the symbol .....
|
Bond dissociation
De |
|
|
What is the equation to describe the anharmonic oscillator?
(Hint: remember the correction added to the harmonic) |
Ev=hωe (ν+1/2)- hωeχe (v+1/2)^2
we = vibrational frequency in the simple harmonic oscillator xe = anharmonicity constant |
|
|
What does the correction to the harmonic oscillator do to the graph for the ANharmonic oscillator?
(Hint: besides it being asymmetrical...) |
The levels get closer together as you approach the dissociation limit.
|
|
|
If a molecule is linear how many vibrations does it have?
|
3N - 5
Where N is the number of atoms in the molecule. |
|
|
If a molecule is non - linear how many vibrations does it have?
|
3N - 6
Where N is the number of atoms in the molecule. |
|
|
What is defined as a "normal vibration"?
|
A normal vibration is where the molecular motion in which the atoms move in phase and with the same frequency.
|
|
|
How many normal vibrations does water have? name all of them.
|
Three
Symmetrical Stretch Bend Asymmetrical Stretch |
|
|
Each of the normal vibrations in a polyatomic molecule has the equation ..... to represent it
(Hint: Ev = ) |
Ev = hwe (v + 1/2)
|
|
|
How many normal vibrations does carbon dioxide have? name all of them.
|
Four
Symmetrical Stretch. Bend (forwards + backwards) Bend (Up + down) Asymmetrical Stretch |
