In the ro-vibrational model for spectra of diatomic molecules, the total rotational and vibrational energy for a given state is: Évj = ū(v + 3) + BJC +1) (Equation 1) where v is the vibrational quantum number and J is the rotational quantum number. Complete the following steps to create a model energy level diagram for a hypothetical diatomic molecule with ✓ = 2000 cm-1 and B = 1 cm-1. i) Draw a horizontal line to represent the ground vibrational...
Shown below is the vibration-rotation spectrum of Hydrogen
Bromide (HBr), this shows transitions between the
v = 0 and v = 1
vibrational levels of the molecule.
From the data, estimate the force constant (spring constant) for
this molecule, given that the relative atomic weights for H and Br
are 1 mu and 80 mu respectively.
Why is this vibrational transition split into 2 series of lines
with a “missing” line in between them at the center? For each of...

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...
2) The vibrational transition from the v = 0 state to the v = 1 state of the CO molecule is found to absorb at 1 = 4.6um. In which region of the spectrum this transition will be taken place? Calculate the vibrational frequency and the force constant for this molecule.
Relative to other lines in a rotational absorption spectrum, the intensity of any given line depends primarily rotational level from which the transition originates. on the size of the population in the In a rotational spectrum of gaseous HCl the most intense absorption line originates in the level for which rotational quantum number J = 3.
