- (Born-Haber cycle); Cl appears to undergo deposition but it isn’t given, overall this question just doesn’t add up to me.With FTIR, where would you expect to see a peak for the Csp2-H stretch?1) How does IR radiation affect absorbing molecules? Name an example molecule that does not absorb IR and briefly explain why. 2) Suppose you are able to figure out, correctly, all of the functional groups for an unknown organic molecule using FTIR. Explain why this might not be sufficient to pin down the exact structure of the molecule. What additional information could be useful? 3) Explain the basic operating principle of an ATR based sampling system? Give the advantages of an ATR-based sampling system compared to one based on direct transmittance of IR radiation in terms of sample thickness and preparation techniques?
