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...
