Seeing Molecules

Throughout organic chemistry, chemists seek to understand the structure and behavior of molecules.

Until now, the emphasis has largely been on explaining why molecules react and how transformations occur.

Spectroscopy introduces a complementary question:

How do chemists determine what molecules actually are?

Spectroscopic methods provide experimental evidence that allows chemists to infer molecular structure.

In many ways, spectroscopy represents the meeting point between theory and observation.

Chapters in This Part

The chapters in this part explore:

• infrared spectroscopy,
  
• nuclear magnetic resonance spectroscopy,
  
• mass spectrometry,
  
• and strategies for combining these techniques to determine molecular structure.

Together, these tools transform chemistry into a process of interpretation and problem-solving.
