Question

What would be the expected IR spectrum of meso-tetraphenylporphyrin?

Answer 1

The structure of meso-tetraphenylporphyrin is as follows: NH HN meso-tetraphenylporphyrin

Aromatic compounds show anumber of absorpti on bands in theIR spectrum The C The C-Cstretching bandsfor aromatic rings usually appear between 1600and 1450 cm A strong absorpti on near 690 cm-1 If this bandis absent,nomono-substitutedringispresent. A secondstrong bandusually appear near 750cm- when the spectrumis taken in a hal ocarbon solvent. The 690 cm bandmay be obscured by thestrong C-X stretch absorption. Thesetypical two peak m onosubstituti on patteren appear in thespectrum of toluene Note:IR spectrum tells only nature of functional group presence. So,by using only IR we cannot find the structure of compound Hstretching peaks for the sp carbon ap
