The vibrational-rotational spectrum of HCl consists of two branches of lines, the R-branch and the P-branch, where the R-branch lines are higher in wavenumber than the P-branch lines. The lines arise from transitions between rotational levels of the v” = 0 vibrational state and rotational levels of the v’ = 1 vibrational state of HCl. What are the quantum numbers of the upper and lower level rotational levels (i.e., J’ and J”) that correspond to the transitions that give rise to the R(7) line and the P(3) in the rotation- vibration spectrum of HCl?

IR absorption soectrum of gasphase hcl question
The infrared absorption spectrum of gas-phase HCl can be analyzed to gain information about both rotation and vibration of the molecule. The absorption lines shown involve transitions from the ground (v = 0) to first excited vibrational state (v = 1) of HCl, but also involve changes in the rational state with a change Delta j = +1 (right branch) and Delta j = -1 (left branch). The splitting of the lines shows...

A. Derive an expression for the rotational partition function in the "high-temperature" limit where qrot can be approximated as an integral. Remember that the rotational energies as a function of rotational quantum number j are given by: ϵ (j) = B j (j + 1) where B is called the “rotational constant” B = ℏ2 /2µ r 2 , and the degeneracy of each "j" state is D(j) = 2j + 1. B. What is the average rotational energy in...
