Question
Given that = 1.931 cm-1 and = 2160.0 cm-1 for CO, calculate the frequencies of the first two lines of the R and P branches in the vibration-rotation spectrum of CO. Given that = 1.931 cm-1 and = 2160.0 cm-1 for CO, calculate the frequencies of the first two lines of the R and P branches in the vibration-rotation spectrum of CO. Given that = 1.931 cm-1 and = 2160.0 cm-1 for CO, calculate the frequencies of the first two lines of the R and P branches in the vibration-rotation spectrum of CO.Explanation / Answer
The given values are
1.931 cm-1 and = 2160.0 cm-1
We know the relation between wavenumber and frequency as
Frequency = Speed of light X wavenumber
a) Frequencey = 3X10^10 cm/sec X 1.913cm^-1 = 5.739 X 10^10 hertz
NOTE: If the value is correctly given (although is sould be 1913 ,and if it is then the answer will be 5739X 10^10)
b) frequencey = 3X10^10 cm/sec X 2160 = 6480 X 10^10 hertz
