How would you use IR and 1H-NMR spectroscopy to distinguish between these two isomeric compounds? For IR, consider the absorption of the carbonyl group. For 1H-NMR, consider the number of signals observed. Select the IR frequency and number of NMR signals that is diagnostic for either isomer a or isomer b. Isomer A: cyclopentanecarboxamide Isomer B: 6-hydroxyhexanenitrile
