10. In the vibrational rotational spectrum of a diatomic molecule, the second line of the P branch (J" = 2 = 1) is observed at 3100 cm and the third line of the R branch (J" = 2- )' = 3) is observed at 3160.cm! Assuming the molecule behaves as a rigid rotor and a harmonic oscillator, calculate the rotational constant (R) and the fundamental vibration wavenumber (V) for the molecule. Hint, you need two equations to solve for the...

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...

Which peaks in your IR spectrum match the known structure of
caffeine? for each diagnostic peak, you should identify its
frequency in wavenumbers and the probable vibration (e.q 2950 cm,
alkane C-H stretch). You should then write a short discussion that
matches the diagnostic peaks to a functional group in caffeine
structure
