Hello students, in this question the rotational spectrum of 19 fluorine gas molecule has been given in which the distance between the two stokes line has been given.
00:11
We have to find out the radius that is the r value.
00:16
We know that b will be equal to h divided by 8 pi square c into i.
00:24
I will be equal to nu r square.
00:27
We are going to substitute this over here.
00:30
B will be equal to h divided by 8 pi square c into nu r square.
00:36
What we have to find is the r square that is r.
00:40
R square will be equal to h divided by 8 pi square c nu into b.
00:46
So first of all we are going to find out the nu value that is the radius mass value which is given by m1 into m2 divided by m1 plus m2.
00:56
As both are the fluorine molecule the mass remains the constant which is given by m square divided by 2m.
01:04
On cancelling m we will get m divided by 2...
