It is important to be able to recognize the significant spectroscopic differences among isomers and other compounds with a similar molecular structure. Generally, analyzing the molecular structures and spectroscopic data to answer a few questions will help you identify how to distinguish among molecules with similar structures. The following questions are useful when using 1H-NMR to accomplish the goal:.
1. Are there differences in the number of expected spectroscopic signals?
2. Are there differences in how many signals are expected in specific chemical shift ranges (i. e. 0 to 70 ppm)?
3. Are there differences in chemical shifts between specific carbons in the isomeric structures that are significantly different? How many 13-NMR signals do you expect for each of the potentiall reaction products shown in the reaction in the introduction between blpheynyl and butanoyl chlorlde?
