The ability to make a positive identification of a drug using UV spectrophotometry is ________ the ability to make a positive identification using IR spectrophotometry.

Question

Quizplus · Accepted Answer

UV spectrophotometry can provide information about the electronic transitions of a molecule and is useful for identifying compounds with conjugated systems. However, IR spectrophotometry provides more detailed information on the functional groups present in a molecule and is therefore better suited for drug identification. Therefore, the ability to make a positive identification using UV spectrophotometry is less than the ability to make a positive identification using IR spectrophotometry.
