This answer is
not correct. There are 2 absorptions in this spectrum that you have interpreted
for this answer. There is an absorption at 3100 cm^{-1} but the
absorption for this answer should be at 3300 cm^{-1}. There is another
band at 1600 cm^{-1} but the absorption for this answer should be at
2100 cm^{-1}. What answer better fits the data?
