For pure rotatioal Raman spectrum of a linear diatomic molecule is rec...
Frequency of the Stokes lines in the pure rotational Raman spectrum of a linear diatomic molecule is given by the formula:
ν_stokes = ν_vibrational - 2B
where ν_vibrational is the frequency of the incident electromagnetic radiation and B is the rotational constant.
To determine the frequency of the two consecutive Stokes lines, we need to consider the change in the rotational quantum number (J) for each line.
Explanation:
1. First Stokes line:
- The first Stokes line corresponds to the transition from J = 0 to J = 1.
- The change in the rotational quantum number is ΔJ = 1.
- Therefore, the frequency of the first Stokes line is given by:
ν_stokes1 = ν_vibrational - 2B
2. Second Stokes line:
- The second Stokes line corresponds to the transition from J = 1 to J = 2.
- The change in the rotational quantum number is ΔJ = 1.
- Therefore, the frequency of the second Stokes line is given by:
ν_stokes2 = ν_vibrational - 4B
Now, let's analyze the options provided:
a) ν_stokes1 = ν_vibrational - 10B
ν_stokes2 = ν_vibrational - 14B
b) ν_stokes1 = ν_vibrational - 2B
ν_stokes2 = ν_vibrational - 4B
c) ν_stokes1 = ν_vibrational + 2B
ν_stokes2 = ν_vibrational - 2B
d) ν_stokes1 = ν_vibrational - 6B
ν_stokes2 = ν_vibrational - 12B
From the above analysis, it is clear that option A is the correct answer because the first Stokes line frequency is ν_vibrational - 2B, and the second Stokes line frequency is ν_vibrational - 4B, which matches with the given options in A.
Hence, the correct answer is option A: ν_stokes1 = ν_vibrational - 10B and ν_stokes2 = ν_vibrational - 14B.
ν_stokes = ν_vibrational - 2B
where ν_vibrational is the frequency of the incident electromagnetic radiation and B is the rotational constant.
To determine the frequency of the two consecutive Stokes lines, we need to consider the change in the rotational quantum number (J) for each line.
Explanation:
1. First Stokes line:
- The first Stokes line corresponds to the transition from J = 0 to J = 1.
- The change in the rotational quantum number is ΔJ = 1.
- Therefore, the frequency of the first Stokes line is given by:
ν_stokes1 = ν_vibrational - 2B
2. Second Stokes line:
- The second Stokes line corresponds to the transition from J = 1 to J = 2.
- The change in the rotational quantum number is ΔJ = 1.
- Therefore, the frequency of the second Stokes line is given by:
ν_stokes2 = ν_vibrational - 4B
Now, let's analyze the options provided:
a) ν_stokes1 = ν_vibrational - 10B
ν_stokes2 = ν_vibrational - 14B
b) ν_stokes1 = ν_vibrational - 2B
ν_stokes2 = ν_vibrational - 4B
c) ν_stokes1 = ν_vibrational + 2B
ν_stokes2 = ν_vibrational - 2B
d) ν_stokes1 = ν_vibrational - 6B
ν_stokes2 = ν_vibrational - 12B
From the above analysis, it is clear that option A is the correct answer because the first Stokes line frequency is ν_vibrational - 2B, and the second Stokes line frequency is ν_vibrational - 4B, which matches with the given options in A.
Hence, the correct answer is option A: ν_stokes1 = ν_vibrational - 10B and ν_stokes2 = ν_vibrational - 14B.
