The vibrational wavenumber of Br2 is 323.2 cm-1.
a) Evaluate the vibrational partition function
without approximation and plot its value as a function of
temperature.
b) Determine the temperature at which the value obtained lies
within 5% of the approximate value.
Calculate the vibrational partition function for CS2
at 500 K given wavenumbers 658 cm-1 (symmetric stretch),
397 cm-1 (bend, two modes), and 1535 cm-1
(asymmetric stretch).
(A) Derive the canonical partition function for a monoatomic
ideal gas. (B) Using the partition function, derive the entropy for
a monoatomic gas.
can you help me with detailed explanations
Why does a change in polarizability in a molecule allow a
vibrational mode to be Raman active? Why does a change in dipole
moment allow a vibrational mode to be IR active? Why do they
differ?
Rotational spectroscopy observe what type of molecule? What is
his energy range? Measured molecule properties.
