QUESTION A high-resolution IR spectrum for HCl is shown below for the v=1+v=0 transition. a) Why there is a series of lines rather than a single vibrational peak. b) If there were only a single vibrational peak that was observed, where should you expect it to be located in the spectrum. c) Calculate the rotational constant in v = 0 and v = 1. d) From the calculated rotational constants in v - 0 and v -1, does the spectrum below reflect the differerIce in their values? Explain? c) Is the bond length shorter or longer in v = 1, compared to v= 0. Show your calculations. f) Why do you think each of the peaks is split into a doublet? Calculate the splitting you would expect from your answer and compare it with the data in the graph. IR Spectrum of HCI, (peak positions are in cm')
