What is the selection rule associated with vibration-rotation spectroscopy?
|
ΔJ = ±1
|
|
|
If ΔJ = +1 then what is the letter given to the transition?
|
This is an R -branch transition.
|
|
|
If ΔJ = -1 then what is the letter given to the transition?
|
This is a P -branch transition.
|
|
|
What is the equation related to vibration-rotation spectroscopy?
(Hint: ΔE = ) |
ΔE = ΔEvib + B1J1 (J1 + 1) - B0J0 (J0 + 1)
|
|
|
What equation allows you to work out the vibrational transition level?
(Hint: ΔEvib = ) |
ΔEvib = hwe + 2hwexe

Name three uses of vibration-rotation spectroscopy...
|
1) Can be used to determine B of heteronuclear diatomic molecules and therefore their bond lengths
2) Polyatomic structure can be determined 3) High resolution IR spectrometers make good gas sensors. |
