In spectroscopy we frequently assumed that at room temperature (298K) all molecules were in the ground vibrational state. Calculate the vibrational partition function for the 2558 cm-¹ band in the IR spectrum of HBr to determine whether this is an appropriate assumption. Make sure that you include enough significant figures to show that you carried out the calculation (i.e. don't just tell me the answer is 1). At what temperature would the vibrational partition function be equal to 2?

* Pls help me with this p.chem hw problem*
Transcribed Image Text:4. In spectroscopy we frequently assumed that at room temperature (298K) all
molecules were in the ground vibrational state.
a. Calculate the vibrational partition function for the 2558 cm-¹ band in the IR spectrum
of HBr to determine whether this is an appropriate assumption. Make sure that you
include enough significant figures to show that you carried out the calculation (i.e.
don't just tell me the answer is 1).
b. At what temperature would the vibrational partition function be equal 2?
